论文摘要
基于平均场波函数的发电机坐标方法框架中，分析了用于计算均匀核中E1和E3过渡强度的旋转公式的有效性。事实证明，那些具有球形或接近球形形状的核会强烈低估使用该公式计算的E1和E3强度，并且对它们的合理评估需要角动量投射波功能。分析了几个具有质子数量或接近魔法数量的同位素链的结果，并将其与实验数据进行比较。角动量投射波函数的使用极大地改善了与稀缺的实验数据的一致性。
The validity of the rotational formula used to compute E1 and E3 transition strengths in even-even nuclei is analyzed within the Generator Coordinate Method framework based on mean field wave functions. It turns out that those nuclei with spherical or near spherical shapes the E1 and E3 strengths computed with this formula are strongly underestimated and a sound evaluation of them requires angular momentum projected wave functions. Results for several isotopic chains with proton number equal or near magic numbers are analyzed and compared with experimental data. The use of angular momentum projected wave functions greatly improves the agreement with the scarce experimental data.
