The Study of Changing Occurs on Two Components Pairing Corrected Partial Levels Density Formulae in Pre-Equilibrium Nuclear Reaction Region with Different Isobaric Nuclei
Ali Dawoud Salloum, Zainab Adil Abdul-Raheem
Abstract: Pairing correction of pre-equilibrium partial levels density (PLD) formula was added to PLD Ericson's formula in order to optimize the theoretical data and make it in agreement with experimental data. There are four types of pairing correction formulae, first type pairing correction, second type (improved pairing correction), third type (exact Pauli correction) and forth type (back shift energy correction). In this paper we studied the effect of different values of proton numbers and neutron numbers in isobaric nuclei on pairing corrected two components PLD formulae. Where we used three isobaric nuclei and the results of PLD of these nuclei for each type of pairing corrected formulae are compared. It is found that the change in Z and N causes a small change in PLD results in case of pairing correction from first type, in case of third type the change in PLD, increase and becomes more in case of forth type and there is no change in PLD results of the second type (improved pairing correction)
