摘要
用推广的汤马斯-费米近似和Skyrme势研究了原子核的高自旋态,应用推转模型给出了含转动的能量密度公式,并计算了^(116)Sn,^(158)Yb和^(240)Pu这三个典型核在不同角动量下的核形变与转动能。计算结果定性地与液滴模型相似,在数值上则有一定差别。计算结果表明,对转动能的量子修正,即使不考虑壳修正,也不能忽略。
Nuclear high spin states are studied in the extended Thomas-Fermi approximation. Explicit formula for rotational energy and various corrections are given. Concrete calculations are performed for three typical nuclei: ^(116)Sn, ^(158)Yb and ^(240)Pu. Qualitatively, the results are similar to that of liquid drop model. Quantum corrections to rotational energy (besides shell corrections) cannot be neglected in a quantitative study.
