O16偶宇称态的结构(Ⅰ)

本文在L-S耦合近似下,并且限于讨论2ω激发的组态,用δ相互作用严格求解了0⁺,2⁺及4⁺态。同时提出一种近似解的办法。即根据粒子的相干效应,可以近似地将双粒子双空穴的结构选为两个粒子相干和两个空穴相干的态。近似解的结果与严格解符合很好。在解释实验上,能量符合得不够好,但在解释O-0跃迁和E2跃迁上却相当成功。

THE STRUCTURE OF THE EVEN PARITY STATES OF O16 (I)

The even parity states of O¹⁶ are treated by taking into account the configuration of 2 ?ω excitation in the L-S coupling scheme and using the δ-interaction of the Wigner type. An approximate method is suggested and the 0⁺, 2⁺, 4⁺, states are solved. Rigorous solutions of the wave functions are obtained as well and compared with the approximate solutions. It is found that they are very close to each other. By using these approximate wave functions the monopole and E2 transition probabilities are calculated, and the results are in nice agreement with experiment, but do not show agreement for the energy level spacings.
