Abstract

The “first chance” spectra of light charged particles and neutrons emitted from ¹⁶⁰Yb produced in the ⁶⁰Ni+¹⁰⁰Mo reaction have been isolated. The same initial temperature for the different evaporated particles and a decrease of the Coulomb barriers for the charged particles are observed. The inverse level density parameter $K= A/ a$ reaches a value of 13.8±0.7 MeV at E_TH≈236 MeV, confirming the decrease of the parameter a at excitation energies above 150 MeV.

Impact of the quenching of shell effects with excitation energy on nuclear level density
2023, Nuclear Physics A
We investigate the nature and impact of shell effects on nuclear level density (NLD) and particle emission probability as a function of temperature in a microscopic theoretical framework of Statistical Model for nuclei ranging from neutron deficient to neutron rich isotopes of Z= 27−35. Critical temperatures are traced for neighbouring even, odd, closed shell and mid−shell nuclei which respond to excitations differently due to their varying stability and structural effects. Importance of the shell effects and shell correction energy is reflected significantly in NLD variation which slowly diminishes with increasing excitation energy indicating the quenching of shell effects. The enhancement of LD parameter with the deformation and rotation and the fade out of enhancement with increasing excitations has been shown. The weakening of magicity of N=28 near the proton drip line has been observed in the inverse level density parameter ‘K’(= A/a) and β variation though it is usually uncommon to see this effect in excited nuclei. Variation of our calculated NLD for odd ⁶⁹As and even ⁷⁰Ge exhibits structural effects and agrees very well with the variation of experimental values. Our evaluated level density parameter ‘a’ values are compared with RIPL-2 (Reference Input Parameter Library) data which show good agreement.
The interplay between the nuclear level density and the separation energy of rotating superheavy nucleus Z = 119 at low temperature regime
2020, Nuclear Physics A
The temperature dependence of the level density parameter and the neutron separation energy are determined under statistical assumptions with regard to the excitation energy using the statistical model code developed in FORTRAN language. The quadrupole deformation parameter and the inverse level density parameter are coinciding well with the experimental results concerning the available literatures. The interplay between the level density and the particle separation energy is displayed graphically to locate the possible neutron magicity and found N=176 suits well at low temperature regime. The excitation energy for the possible formation of ${}^{295}119$ is predicted as 33.3 MeV.
Dependence of spin induced structural transitions on level density and neutron emission spectra
2019, Nuclear Physics A
The impact of spin induced deformation and shape phase transitions on nuclear level density and consequently on neutron emission spectra of the decay of compound nuclear systems ¹¹²Ru to ¹²³Cs ( $N = 68$ isotones) is investigated in a microscopic framework of Statistical theory of superfluid nuclei. Our calculations are in good accord with experimental data for evaporation residue of ¹¹⁹Sb^⁎ and ¹⁸⁵Re^⁎ and show a strong correlation between spin induced structural transitions and NLD. We find that the inverse level density parameter ‘K’ increases with increasing spin for all the systems, but it decreases with a deformation or a shape change that results in the enhancement of level density and emission probability. A sharp shape phase transition from oblate to uncommon prolate non-collective in well deformed nuclei leads to band crossing and enhancement of level density which fades away while approaching sphericity at or near shell closure manifesting shell effects.
Fragment properties of fragmenting heavy nuclei produced in central and semi-peripheral collisions
2009, Nuclear Physics A
Fragment properties of hot fragmenting sources of similar sizes produced in central and semi-peripheral collisions are compared in the excitation energy range $5 – 10 A MeV$ . For semi-peripheral collisions a method for selecting compact quasi-projectiles sources in velocity space similar to those of fused systems (central collisions) is proposed. The two major results are related to collective energy. The weak radial collective energy observed for quasi-projectile sources is shown to originate from thermal pressure only. The larger fragment multiplicity observed for fused systems and their more symmetric fragmentation are related to the extra radial collective energy due to expansion following a compression phase during central collisions. A first attempt to locate where the different sources break in the phase diagram is proposed.
Estimate of average freeze-out volume in multifragmentation events
2005, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
An estimate of the average freeze-out volume for multifragmentation events is presented. Values of volumes are obtained by means of a simulation using the experimental charged product partitions measured by the 4π multidetector INDRA for ¹²⁹Xe central collisions on ^natSn at $32 A MeV$ incident energy. The input parameters of the simulation are tuned by means of the comparison between the experimental and simulated velocity (or energy) spectra of particles and fragments.
Particle multiplicities in the fission-like reactions of 340 MeV 28<sup>Si</sup> on 232<sup>Th</sup>
2004, Nuclear Physics A
Pre-scission and post-scission multiplicities of neutrons and alpha particles have been simultaneously measured for the fission-like reactions of 340 MeV ²⁸Si on ²³²Th. Dynamical model calculations using HICOL code predict that about 90% of the observed events are of quasi-fission type while the remaining 10% are from compound nucleus fission decay. Moving source fits were carried out to the observed neutron and alpha particle spectra, measured at different angles with respect to the fragment directions. The pre-scission and post-scission neutron multiplicities are deduced to be 8.7±2.0 and 9.4±2.0, respectively. The corresponding multiplicity values for alpha particles are found to be 0.22±0.08 and 0.1±0.03. From the measured post-scission neutron multiplicity, it is inferred that about 65±20 MeV of the initial excitation energy remains at scission. This may be compared to the value of 85±30 MeV estimated from PACE2 statistical model calculations, adjusted to reproduce the measured pre-scission neutron multiplicity. From a comparison of the Statistical Model predictions with the measured pre-scission neutron multiplicity, the fission delay is estimated to be of 5⁺⁷₋₃×10⁻²⁰ s which overlaps with the average duration of fission-like process from the contact to the scission point (2×10⁻²⁰ s) as determined from HICOL-based dynamical calculations. For the delay time deduced as above, the pre-scission alpha particle multiplicity calculated by the PACE2 code is about a factor two larger than the experimental one, demonstrating the difficulties in modelling the alpha particle emission from highly elongated shapes that characterize the fissioning system from the contact point to scission.
