Analysis of barrier distributions data for16O + 64Zn reaction at sub-barrier energies

The barrier distribution data for the 16O + 64Zn reaction at energies spanning around the no minal barrier are examined by employing symmetric-asymmetric Gaussian barrier distribution (SAGBD) approach. The cumulative role of dominant channel couplings in the SAGBD method are determined in terms of the channel coupling parameter λ and percentage decrease of fusion barrier VCBRED with reference to nominal Coulomb barrier. The non-zero and positive values of these parameters for the studied system quantitively measure the influences of dominant intrinsic channels originated from the structure of the participants. The barrier distribution data of 16O + 64Zn reaction is quantitatively as well as qualitatively explained by SAGBD outcomes.

Comparative Analysis of 13,14C Induced Reactions on 232Th Target

We have investigated the pairing and magicity effect in context of a comparative study of 13,14C induced reactions on 232Th target at energies in the vicinity of Coulomb barrier. The fission distribution and related properties are explored in terms of the summed-up preformation probabilities. The barrierpenetrability is found to be higher for fragments emitted from 246Cm* formed in 14C+232Th reaction than those emitted in the fission of 245Cm*, leading to higher magnitude of cross-section for earlier case. The DCM calculated fusion-fission cross-sections using ΔR=0 fm are normalised to compare with the available experimental data. The calculations are done for spherical shape of fragments and it will be of further interest to explore the fission mass distribution after the inclusion of deformations.
