Effect of β 6 deformation parameter on fusion cross-section and barrier distribution

Effect of β 6 deformation parameter on fusion cross-section and barrier distribution The effect of hexacontatetrapole deformation parameter on both the fusion cross-section and the barrier distribution have been studied for U238 + O16 nuclear pair using microscopically derived heavy ion (HI) potential. A method was described to extend the calculation of HI potential between two spherical nuclei using density dependent finite range NN forces to the spherical-deformed interacting pair. Density dependent and density independent effective NN forces were used in the generalized double folding model to derive the HI potential. We found that positive β 6 has large effect on both the fusion cross-section and the barrier distribution in the presence of a small value of hexadecapole deformation parameter β 4. In this case the fusion cross-section is less sensitive to the negative value of β 6. In the presence of a large value of β 4, negative and positive β 6 values affect the fusion cross-section and have a small effect on the barrier distribution. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Physica Hungarica Series A, Heavy Ion Physics Springer Journals

Abstract

The effect of hexacontatetrapole deformation parameter on both the fusion cross-section and the barrier distribution have been studied for U238 + O16 nuclear pair using microscopically derived heavy ion (HI) potential. A method was described to extend the calculation of HI potential between two spherical nuclei using density dependent finite range NN forces to the spherical-deformed interacting pair. Density dependent and density independent effective NN forces were used in the generalized double folding model to derive the HI potential. We found that positive β 6 has large effect on both the fusion cross-section and the barrier distribution in the presence of a small value of hexadecapole deformation parameter β 4. In this case the fusion cross-section is less sensitive to the negative value of β 6. In the presence of a large value of β 4, negative and positive β 6 values affect the fusion cross-section and have a small effect on the barrier distribution.
