摘要:

通过在RCNP进行的295 MeV质子非弹性散射实验,提取了稳定的偶数质量锡同位素112,114,116,118,120,124的偶极极化率。从能量密度泛函的预测不能同时解释目前的数据和208 Pb的极化率。极化率在相邻同位素的演变表明在120 Sn扭结,而所有的模型结果显示,包括配对校正后,与质量数的近线性增加。

英文摘要:

The dipole polarizability of stable even-mass tin isotopes 112,114,116,118,120,124 was extracted from inelastic proton scattering experiments at 295 MeV under very forward angles performed at RCNP. Predictions from energy density functionals cannot account for the present data and the polarizability of 208Pb simultaneously. The evolution of the polarizabilities in neighboring isotopes indicates a kink at 120Sn while all model results show a nearly linear increase with mass number after inclusion of pairing corrections.
