Abstract

Proton single-particle properties of even–even tin isotopes in the mass number range between 100 and 132 were calculated on the basis of the dispersive optical model. The possibility of describing data on the charge radius \(r_{\mathrm{ch}}\) was studied. A decrease in the rate of growth of \(r_{\mathrm{ch}}\) with increasing \(N\) in the region of \(N>76\) was obtained via increasing the energy interval in the vicinity of \(E_{\mathrm{F}}\) where the imaginary part of the potential used is close to zero. The predictive power of the dispersive optical model for the density distribution in nuclei far from the beta-stability valley was demonstrated.

摘要

根据色散光学模型，计算了质量数在100到132之间的偶数偶数锡同位素的质子单粒子性质。研究了在电荷半径\（r _ {\ mathrm {ch}} \）上描述数据的可能性。在的生长速率的降低\（R _ {\ mathrm {CH}} \）随\（N \）中的区域\（N> 76 \）经由在附近增大能量间隔获得\ （E _ {\ mathrm {F}} \），其中所用电势的虚部接近零。证明了色散光学模型对远离β稳定性谷的原子核中的密度分布的预测能力。
