Tourism, an essential engine for economic development, also raises issues that lean towards the aspect face to with environmental, socio-cultural, and well-being of local community. Bodhgaya, a UNESCO World Heritage Site one holiest pilgrimage sites in Buddhism, reflects complexities tourism-driven development. Tourism has contributed economy but manifested social-economic inequality, stressed facilities, put pressure on cultural heritage environment. This research elaborates relationship...
Background: Enhanced prescission neutron multiplicity (${\ensuremath{\nu}}_{\mathrm{pre}}$) over statistical model calculations assuming Bohr-Wheeler fission width is explained using Kramers' incorporating dissipative effects. The dissipation strength obtained from such studies reported significant effect of the shell closure $N=126$ fissioning system as well nuclear temperature. dependence on and temperature also attributed to choice input parameters in calculations.Purpose: We investigate...
The pre- and post-scission neutron multiplicities are measured for the fission of 208Rn, populated with reactions 30Si+178Hf 48Ti+160Gd in excitation energy range 54.5 - 80.8 MeV. We found significant differences pre-scission these two systems. Also, both exhibit an enhancement multiplicity respect to existing data 16O+194Pt reaction populating 210Rn. compared theoretical predictions obtained from Langevin dynamical model fission. Dynamical simulations also performed estimate capture...
The multinucleon transfer reaction or incomplete fusion (ICF) is a powerful tool to study fission of exotic nuclei that cannot be formed by stable heavy-ion reactions. In the present work, mass distributions fragments (FFs) from fissioning $^{241,242,243,244}\mathrm{Pu}$ and $^{240,241}\mathrm{Np}$ populated in ICF reactions on $^{6,7}\mathrm{Li}+^{238}\mathrm{U}$ systems have been studied. Among these, $^{244}\mathrm{Pu},\phantom{\rule{0.16em}{0ex}}^{243}\mathrm{Pu}$, $^{241}\mathrm{Np}$...
Neutron multiplicities, folding angle distribution, mass and mass-energy distribution are measured for the compound nucleus $^{210}\mathrm{Po}$ populated through $^{12}\mathrm{C}+^{198}\mathrm{Pt}$ reaction at an excitation energy of 61.6 MeV. The neutron multiplicities compared with statistical model code joanne2 to extract total fission time nucleus. $({\ensuremath{\tau}}_{\mathrm{tot}})$ obtained this system is...
Fission fragment angular distributions for three reactions, $^{19}\mathrm{F}+^{182}\mathrm{W},^{19}\mathrm{F}+^{187}\mathrm{Re}$, and $^{19}\mathrm{F}+^{193}\mathrm{Ir}$, are measured in the laboratory energy range of 82--120 MeV. Extracted fission cross sections present systems as well those others from literature $(^{19}\mathrm{F}+^{192}\mathrm{Os},^{19}\mathrm{F}+^{194}\mathrm{Pt}$, $^{19}\mathrm{F}+^{197}\mathrm{Au})$ compared with predictions a statistical model which takes into account...

The pre-scission α-particle multiplicity (αpre), measured in 16O (96 MeV) + 232Th reaction, is observed to be significantly lower than the global trend reported earlier. Statistical model calculations also show a much shorter fission-time reproduce experimental αpre. By assimilating previous measurements, it that αpre makes changeover from high very low value while crossing Businaro Gallone point mass asymmetry entrance channels heavy-ion induced fission of 232Th.

Fission process is strongly influenced by entrance channel dynamical variables. Among these, the nuclear charge product, mass asymmetry and deformation play important role in fission dynamics. Reaction characteristics are distinguished investigating properties of angular distributions. Experiments using actinide targets challenging due to many conflicting results making unambiguous identification quasi-fission difficult. At IUAC accelerator facility experiments have been performed make a...
