发展超越平均场理论是当前核理论研究的基本课题。采用自己提出的新公式~[1-2],实现了投影后变分的数值计算~[3]。该方法的基本思想如下:从现实哈密顿量出发(以USDB相互作用为例),对其进行HFB平均场计算。在所得平均场基础上,首次作角动量(J)、同位旋(T)、质量数(A)三者同时投影(即JTA投影)。最后,需要尝试各种 The development of theory beyond the average field is the basic issue of current nuclear theory. Using the new formula [1-2] proposed by myself, the numerical calculation of the variation after projection [3] is realized. The basic idea of ​​this method is as follows: Starting from the actual Hamiltonian (taking the USDB interaction as an example), the HFB mean field calculation is performed. On the basis of the average field obtained, for the first time, the angular momentum (J), isospin (T) and mass (A) are simultaneously projected (ie JTA projection). Finally, you need to try all kinds
