核平均场加一般对力哈密顿量严格解的新代数方法

New Algebraic Approach for an Exact Solution of the Nuclear Mean-Field Plus Orbit-Dependent Pairing Hamiltonian

介绍了导出平均场加一般对力核多体问题粒子数守恒严格解的无穷维李代数方法．作为例子，计算了等价于普适ｄｓ壳相互作用情形下１８－２６Ｏ偶偶核素壳模型结果的严格解，并与强度可分离对力（ＳＳＰ）及等强度对力（ＥＳＰ）的结果进行了比较．

AN infinite dimensional algebraic approach is introduced to derive exact particle-number conserving solutions of the nuclear mean-field plus general orbit-dependent pairing Hamiltonian. As an example, exact solutions of the theory for even-even 18-26O, which are equivalent to the shell-model results for the universal ds-shell interaction are calculated and compared with the corresponding Separable Strength Pairing (SSP) and Equal Strength Pairing (ESP) results.
