Fragment mass identification and related aspects in the decay of 40Ca* and 39K* nuclei

The dynamics involved in the decay of light mass nuclei formed in asymmetric channels 12C + 28Si, 11B + 28Si and 12C + 27Al have been investigated using the dynamical cluster-decay model (DCM). In reference to the experimentally measured charge particle cross-sections, the fragment masses contributing towards the decay of 40Ca* and 39K* nuclei have been identified using spherical choice of fragmentation. Also, the role of entrance channel has been investigated by studying the decay of 39K* nuclear system formed in two different reactions at same excitation energy. The behavior of fragmentation potential, preformation probability, penetrability and emission time, is analyzed to figure out the favorable mass fragments, their relative emergence and the entrance channel effects observed in the decay of light mass nuclei. In addition to this, the cross-sections for the light particles (LPs) and heavier charge fragments have been estimated for the compound nucleus (CN) decay. Besides this, one of the noncompound nucleus (nCN) process, deep inelastic collision (DIC) has been addressed in context of DCM approach for the first time. The cross-sections obtained in framework of DCM for both CN and nCN processes are found to have nice agreement with the available experimental data.

Coping strategies adopted by dual career couples in it sector in India – A case study

With the increasing influx of women in IT sector work-life challenges has also increased. Many working couples are facing an imbalance between work and family domain. They are adopting both healthy and unhealthy coping strategies to strike a balance between work and life. They are going for flexitime working strategy, self-absorbed outlook strategy, spousal and social support for coping these work-life challenges.

Dynamics of 16,18O-induced reactions using Ni, Ge and Mo targets

Dynamical cluster decay model (DCM) based on the collective clusterization approach is employed to explore the dynamics of various even-mass Zr isotopes formed in 16O-induced reactions. In reference to the measured fusion cross-section data, various decay modes contributing towards 86,88,90,92Zr∗ nuclei are investigated. Also, the role of deformations and orientation degree of freedom is analyzed by comparing results with spherical choice of fragmentation. In addition to this, the effect of entrance channel is explored for 92Zr∗ and 76Kr∗ nuclei formed in 16O and 18O-induced reactions. Besides this, the dynamics of relatively heavier mass Sn isotopes is exercised using 16O and 18O projectiles. The DCM calculated decay cross-sections find good agreement with available experimental data.

Decay of Zr isotopes and related nuclear structure effects using the collective clusterization approach

The reaction dynamics of various even-mass Zr isotopes is studied using the collective clusterization approach of the dynamical cluster decay model (DCM). The role of iso-spin (N/Z ratio) and deformation is explored by analysing the decay pattern of various Zr-nuclei formed in 16O induced reactions. Also, the entrance channel effect is investigated by studying the decay of the 92Zr* nuclear system formed in two different reactions at comparable excitation energy. In order to obtain a clear picture of the dynamics involved in the reactions under consideration, the behavior of the fragmentation potential and the preformation factor is analyzed. The DCM calculated cross-sections find nice agreement with available experimental data.

Dynamics of [sup 6]Li+[sup 152]Sm→[sup 158]Tb∗ reaction across the Coulomb barrier

The neutron cross-section and the complete fusion cross-section data is available for 6Li+152Sm→158Tb*→A1+A2 reaction at various lab energies ranging from ELab = 20 MeV -40 MeV, where the effects of target deformation and projectile break-up are addressed. Here in this work, we have emphasized on the deformation (and orientation) effects in the decay of 158Tb* nucleus in the framework of dynamical cluster decay model (DCM). The cross-sections obtained through DCM based calculations find nice agreement with the reported experimental data across the Coulomb barrier. The available cross-sections are fitted for spherical and β2-deformed fragmentation paths with the effects of static β2(0) and dynamic β2(T) deformations also included into it. This provides a nice description of the role of deformation in the decay of 158Tb* nucleus. Besides this, comparative analysis with equatorial (compact) and polar (non-compact) configurations is worked out. As the polar orientations start appearing at sub-barrier energies...
