Single-particle structure of the N = 20, 28 isotones within the dispersive optical model

摘要: The neutron single-particle characteristics of the $ N = 20, 28$ isotones at 8 < Z 30$ were calculated within dispersive optical model. global parameters spin-orbit and imaginary parts potential as well surface absorption independent on neutron-proton asymmetry increased diffuseness large excess used in calculations. suitability to predict evolution structure nuclei near drip line was investigated. following results are agreement with available experimental data: reduction particle-hole energy gaps, degeneration 1f_{7/2}$ 2p$ states then a change 1f_{7/2}$, 2p_{3/2}$ level sequence more rapid 2p$-splitting comparison 1f$-splitting decreasing. predictive power model respect neutron-rich is demonstrated.
