Abstract

Proton and deuteron inelastic scattering experiments, performed with an energy resolution of 12–15 keV, have been used to study negative-parity states of vibrational and transitional nuclei with mass between 98 and 150. The analysis has been focussed on the isovector components, on the quadrupole-octupole two-phonon states and on the fragmentation of the octupole strength. This latter displays a regular dependence on the product of proton and neutron valence particle numbers and is satisfactorily reproduced by IBM-1 + f-boson calculations. Other features of the experimental spectra, as the relative positions of the 3⁻ states, exhibit a dependence on the ratio of valence particle numbers and indicate that a IBM-2 approach might be more appropriate.

Nuclear Data Sheets for A=100
2021, Nuclear Data Sheets
Evaluated experimental data are presented for 15 known nuclides of mass 100 (Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn). Recommended values are given for level parameters, γ and β radiations, and other spectroscopic information. No excited states are known in ¹⁰⁰Rb and ¹⁰⁰Sn. Except for isotopic identification, no information is available for the decay of the ¹⁰⁰Kr isotope, and limited information is known about the decay properties of the ¹⁰⁰Sn isotope. According to Fig. 2 (A/Q versus counts plot) and as mentioned in the text in 2021Su01, ¹⁰⁰Br isotope was not observed, although, discovery of ¹⁰¹Br was claimed in this work. In the case of ¹⁰⁰Pd, the agreement in the orderings of the γ-ray cascades and γ-ray inventory between various studies of high-spin structures remains poor at high excitation energies (>9 MeV). For ¹⁰⁰Y, the assignments of the two previously known half-lives to the respective states (g.s. and the 145-keV isomer) remain to be established. This work supersedes earlier full evaluations of A=100 by 2008Si01, 1997Si09, 1990Si05 and 1974Ko37.
Nuclear Data Sheets for A=98
2020, Nuclear Data Sheets
Experimental spectroscopic data on nuclear structure and decay are evaluated for known nuclides of mass 98 (Br, Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In). Detailed evaluation results of individual reactions and decays are presented together with the Adopted values that are recommended for level properties, γ and β radiations, and other spectroscopic information. ⁹⁸Mo remains as the most extensively studied nuclide via various reactions and decays. Level schemes of Sr, Y, Zr, Tc, and Pd nuclides in this mass chain are also well established to date; while Kr, Rb, Nb, Ag and Cd are amongst the least-studied ones for excited states, with only limited data available for each. On the neutron-rich side, ⁹⁸Br has been identified in the ⁹Be(²³⁸U,F) reaction, but no spectroscopic data are yet available, while for ⁹⁸In on the proton-rich side, only the ground state and an isomer are known with half-lives measured but their spin-parities and the absolute level energy of the isomer yet to be determined. While ⁹⁸Ru and ⁹⁸Rh have also been extensively studied, large discrepancies exist between the high-spin sections of the proposed level schemes in different measurements, and these need to be clarified and resolved with further experimental investigations to improve the currently-adopted ones, which have been selected from the measurements with higher statistics, considering no other criteria of preference. This work supersedes all the earlier evaluations of A=98 (2003Si07, 1998Si18, 1992Si21, 1983Mu21, 1974Me34).
Energy surfaces of <sup>100–106</sup>Ru isotopes in the U(5)↔SO(9) transitional region
2017, Nuclear Physics A
The critical behavior of ^100–106Ru isotopes is investigated in the $U (5) \leftrightarrow SO (9)$ transitional region of the spd-interacting boson model. We have developed a solvable extended transitional Hamiltonian based on affine $SU (1, 1)$ Lie algebra within the framework of the spd-interacting boson model. Also, we have used the catastrophe theory in combination with coherent state formalism to generate the energy surfaces of considered isotopes. The parameters of the transitional Hamiltonian are determined via Least-Square Fitting (LSF) to the experimental data of Ru isotopes to describe both positive and negative parity states and also $E (1)$ and $E (2)$ transition probabilities. Results describe experimental counterparts with satisfactory degrees of agreement and also suggest ¹⁰⁰Ru as the best candidate for the critical point of this transitional region.
Nuclear Data Sheets for A = 146
2016, Nuclear Data Sheets
Evaluated nuclear structure and decay data for all nuclei within the A = 146 mass chain are presented. The experimental data are evaluated and best values for level and gamma-ray energies, quantum numbers, lifetimes, gamma-ray intensities, and other nuclear properties are recommended. Inconsistencies and discrepancies that exist in the literature are noted. This work supersedes the earlier evaluation by L.K. Peker, J.K. Tuli (1997Pe22), published in Nuclear Data Sheets 82, 187 (1997).
Nuclear Data Sheets for A = 112
2015, Nuclear Data Sheets
Evaluated nuclear structure and decay data for all nuclei within the A = 112 mass chain are presented. The experimental data are evaluated and best values for level and gamma-ray energies, quantum numbers, lifetimes, gamma-ray intensities, and other nuclear properties are recommended. Inconsistencies and discrepancies that exist in the literature are noted. This work supersedes the earlier evaluation by D. De Frenne and E. Jacobs (1996De55), published in Nuclear Data Sheets 79, 639 (1996).
Nuclear Data Sheets for A=150
2013, Nuclear Data Sheets
The experimental results from the various reaction and decay studies leading to nuclides in the $A = 150$ mass chain have been reviewed. These data are summarized and presented, together with the adopted level schemes and properties, for the nuclides from Cs(Z=55) through Lu(Z=71). This evaluation replaces the previous evaluation by E. der Mateosian and J. K. Tuli (1995De28), which appeared in Nuclear Data Sheets 75, 827 (1995).
