利用角动量投影技术，我们提出了一种可靠地计算原子核集体转动量子谱的方法。该方法利用了几个具有不同旋转频率的曲柄平均场态，并在执行投影后，在组态混合或生成坐标方法的意义上叠加它们;该想法最初由Peierls-Schulless在1962年提出。据发现，作为配置混合的结果的频谱并不基本上取决于所选择的组的曲柄频率，如果在混合中使用的平均场状态的数量大于某个小的值。我们应用这种方法的三个例子采用Gogny D1 S有效相互作用，并表明它是有用的，通过角动量投影方法来研究高自旋转动带。
By employing the angular momentum projection technique we propose a method to reliably calculate the quantum spectrum of nuclear collective rotation. The method utilizes several cranked mean-field states with different rotational frequencies and they are superposed in the sense of the configuration mixing or the generator coordinate method, after performing the projection; the idea was originally suggested by Peierls-Thouless in 1962. It is found that the spectrum as a result of the configuration mixing does not essentially depend on chosen sets of cranking frequencies if the number of mean-field states utilized in the mixing is larger than a certain small value. We apply this method to three examples employing the Gogny D1S effective interaction and show that it is useful to study high-spin rotational bands by means of the angular momentum projection method.
