    Notes: Abstract: The inclusive energy spectra of light charged particles, such as, α, p, d and t, evaporated from the hot 31P nucleus at an excitation energy E *∼ 60 MeV, have been measured at various angles. The compound nucleus 31P has been populated using two different entrance channel configurations; i.e., 7Li (47 MeV) + 24Mg and 19F (96 MeV) + 12C reactions, leading to the same excitation energy of the compound system. It has been observed that the spectra obtained in the 7Li (47 MeV) + 24Mg reaction follow the standard statistical-model prediction with a spherical configuration of the compound nucleus. But, the spectra obtained in the 19F (96 MeV) + 12C reaction deviate from similar predictions of the statistical model both on higher- as well as on lower-energy sides. Considerable deformation was required to be incorporated in the calculation in order to reproduce the measured-energy spectra in this case. Dynamical trajectory model calculations were not found to play any significant role in explaining the differences in behaviour between the two cases under study. The observed discrepancy has been attributed to the difference in the angular-momentum distributions of the compound nuclei formed in the two reactions.

    Intermediate width structures in the reaction50Ti(p, n)50V (1983)

    Notes: Abstract The total (p, n) reaction cross section for50Ti has been measured from threshold upto about 4.9 MeV proton energy, with fine energy resolution. The excitation function averaged over about 100 keV energy interval exhibits “intermediate width structures”. Detailed statistical analysis of the data has revealed the presence of two kinds of structures having average widths which are characteristic of the compound nuclear and intermediate reaction mechanisms. The level spacings of these intermediate structures are consistent with Izumo's partial equilibrium model.

    The real part of the nucleon-nucleus optical potential (1983)

    Notes: Abstract Volume integrals of the real part of the proton and neutron optical potentials computed using the existing phenomenological analyses forA=12–209 and for a range of nucleon energies (E p =10–180 MeV;E n = 8–150 MeV) have been fitted with an empirical experession. The magnitude and the energy dependence of the isoscalar, the isovector and the Coulomb components of the real part of the potential determined from this empirical procedure agree well with those predicted by the microscopic approach.

    Influence of pre-fission neutron emission on fission fragment angular distribution for the system209Bi +16O (1994)

    Notes: Abstract The data of fission fragment anisotropies measured for the system16O +209Bi in the centre of mass energy region of 73 to 95 MeV have been compared with the saddle point statistical model calculations. The corrections to the nuclear temperature and the spin distribution arising due to pre-fission neutron emission have been made. While the resultant calculations reproduce very well the data in the near- and sub-barrier energy regions, they deviate from the data at higher energies. This observation is similar to what was already reported for16O +208Pb system.

    Fission fragment anisotropies for 19F +209Bi system (2000)

    Notes: Abstract: The fission fragment angular distributions have been measured for the system 19F +209Bi over a range of bombarding energies from 88.0 MeV to 125.6 MeV. The measured fission fragment anisotropies are in agreement with the saddle point statistical model calculations in the above energy range. Combining these data with those available for 11B, 12C, 14N, 16O and 18O +209Bi, 208Pb systems, it is concluded that the spherical target plus projectile systems behave “normal” from near- to above – barrier energies. This observation is in contrast to the “anomalous” anisotropies exhibited by the deformed actinide target – projectile systems at near – barrier energies.

    Heavy-ion total reaction cross sections (1984)

    Notes: Abstract A one-parameter expression has been found which predicts with a smaller χ2 than previous expressions, the total reaction cross sections for a large number of heavy-ion systems covering a wide energy range. The expression uses an interaction radius which is a sum of the equivalent uniform matter radii of the interacting nuclei plus and energy-dependent term.

    Notes: Abstract The absolute differential cross sections for the40Ca(α,α)40Ca reaction have been measured in the bombarding energy range from 4.33 to 5.68 MeV at the four laboratory angles 85°, 125°, 141° and 165°. An analysis of the data using multilevelR matrix theory has provided the spin-parities and widths of 29 levels in the compound nucleus44Ti. A comparison has been made with the levels deduced from the (α,γ) reaction and existing theoretical calculations of44Ti levels.

    Notes: Abstract Fusion cross sections for projectiles ranging from4He to40Ar and for compound systems with mass numbers between 24 and 242 are successfully described by an empirical four parameter expression. The energy-dependence is similar to that of Horn and Ferguson. The mass-dependence is more appropriately described in terms of the reduced mass and the geometrical dependence is given in terms of the radii of the interacting nuclei. The maximum fusion cross section and the energy at which the maximum occurs are predicted in agreement with the experimental data.
