Analysis of dynamical behavior of reactions associated with 118,120,122Xe⁎ isotopes

Abstract

In reference to recent experiment, the dynamical aspects of reactions forming even mass isotopes of 118,120,122Xe⁎ nuclei are examined using the collective clusterization approach and the ℓ-summed Wong model. The role of excitation energy (or temperature), deformations, orientations and angular momentum etc. has been investigated for the 28Si + 90,92,94Zr reactions. In order to account for the role of deformations, the evaporation residue (ER) cross sections of 122Xe⁎ nucleus have been studied in reference to the available experimental data by using spherical as well as deformed fragmentation approach. We have used optimum and compact orientations respectively for β2 alone and for β4 included, which inturn provide nice agreement with the available experimental cross-sections. Also, the effect of isospin (N/Z ratio) of decay fragments has been explored in view of the fragmentation analysis and preformation probability of 118,120,122Xe⁎ nuclei. Additionally, the role of projectile nucleus is also explored by studying the fragmentation path of 118Xe⁎ nucleus in comparison to 123Ba⁎ system. Further, the ER cross-sections have been predicted for various even mass isotopes of 116,118,120,124Xe. In addition to this, to explore the fusion characteristics of 28Si + 90,92,94Zr reactions, the Wong model as well as the ℓ-summed Wong model has also been employed. Here also, the role of deformation in formation of 122Xe⁎ nucleus has been examined and the calculated cross-sections find decent agreement with the experimental data.
