Abstract.

The total cross section, the intermediate mass fragment (IMF) production cross section, and the cross section for the formation of light particle (LP) for the decay of 48Cr* formed through the entrance channel 24Mg + 24Mg , have been evaluated using the barrier penetration model, taking the scattering potential as the sum of the Coulomb and nuclear proximity potential, for various ECM values. The computed results have been compared with the available experimental data of the total cross section corresponding to E CM = 44.4 MeV for the entrance channel 24Mg + 24Mg , and were found to be in good agreement. The experimental values for the LP production cross section for the channel 24Mg + 24Mg were also seen to be agreeing with our calculations. Hence we have extended our studies and have thus computed the total cross section, IMF cross section and LP cross section for the decay of 48Cr* formed through the other two entrance channels 36Ar + 12C , and 20Ne + 28Si with different ECM values. It was found that the computed total cross sections for the entrance channel 36Ar + 12C with E CM = 47 MeV agree well with the corresponding experimental values. Hence, we hope that our predictions on the evaluations of the IMF cross sections and the light charged particle cross sections for the decay of 48Cr* , formed through the two entrance channels 36Ar + 12C , and 20Ne + 28Si , can be used for further experimental studies.
