Temperature Dependence of Nuclear Potentials and its Relevance

Abstract

In reference to the recent developments in the field of nuclear structure and reaction dynamics in low energy range, it has been observed that a large number of experiments are performed at the extreme conditions of temperature, energy, angular momentum etc.. Many such experiments are being planned in order to establish the dynamical behaviour of exotic nuclear systems. In order to complement these advancements in nuclear experimentations, it becomes essential and important to develop the theoretical aspects of related phenomena. One of the major requirement in this front is the availability of realistic nuclear potentials and their proper and accurate temperature dependence. In order to meet this challenging task the nuclear theory group at Thapar University Patiala and Punjab University Chandigarh, have done a very useful effort to establish temperature dependence on nuclear potential. In this effort the bulk constant α(0) and proton-neutron asymmetry constant aa of Seeger et.al. are refitted at T=0 for all isotopes of periodic table upto Z=118. In this thesis, I have reviewed the nuclear mass formulae and their possible temperature dependence. For the purpose, a chronological development of nuclear potentials is presented in a systematic manner. The need and requirement of temperature dependence on these nuclear potentials is discussed in detail. An effort is made to find out the
