在扩展的B-F理论下中重核的中子皮和中子晕

S. V. Lukyanov, A. I. Sanzhur

摘要:

在扩展的费密近似下计算了中重核的中子皮和中子晕分布。用直接变分法计算了有效类Skyrme力。均方根半径$Δr_{np}$作为皮肤和晕状条款的总和的等矢量移动的解析表达式。光环和皮肤项的贡献$Δr_{np}$被发现是近似相等的。

英文摘要:

The neutron skin and halo distributions in medium and heavy nuclei are calculated within the extended Thomas-Fermi approximation. Calculations are carried out for the effective Skyrme-like forces using the direct variational method. The analytical expression for the isovector shift of the rms radii $Δr_{np}$ as a sum of skin- and halo-like terms is obtained. The contribution of halo and skin terms to $Δr_{np}$ are found to be approximately equal.
