Theoretical Study of the Similarity Between Nuclei with four Valence Nucleons in A = 208, 132 and 68 Regions

摘要

One of the most interesting topics in nuclear structure is the study of nuclei near the limits of particle stability. Much attention is currently being focused on nuclei with few valence nucleons around Z=28, 50 and 82, in particular the 68Ni, 132Sn and 208Pb neighbors. We are interested of the even-even isobars 72Ni, 72Ge and 72Zn in 68Ni region, 136Sn, 136Xe and 136Te in 132Sn region, 212Pb, 212Rn and 212Po in 208Pb region. The calculation of energies spectra using the effective interactions JUN45M, CWΔ5082 and KHP shows a good agreement with the available experimental data for the energie levels and their sequences. We have extended the existed similarity between lead and tin regions to the Nickel region.
