随着放射性核束的发展,人们对奇特核区的幻数或者壳关闭问题越来越感兴趣。标准壳模型给出2、8、20、28、50、82和中子数126为原子核幻数,这对于理解核结构具有非常重要的意义。比双幻核更稀少的是双半壳核,在sd壳层上面,只有1248Si、1348Si、2448Cr和17660Dy4个双半壳核。对于研究集体转动运动,重核16760Dy比较理想。目前,实验上也正在对靠近双半壳核16760Dy晕转谱 With the development of radioactive nuclear beam, people are more and more interested in the magic number or the shell closing problem in the special nuclear region. The standard shell model gives 2, 8, 20, 28, 50, 82 and neutron number 126 for nuclear magic numbers, which is very important for understanding the nuclear structure. More rare than the double phantom nuclear double shell half nuclear shell, above the sd shell, only 1248Si, 1348Si, 2448Cr and 17660Dy4 double half shell nucleus. For the study of collective rotation movement, heavy nuclear 16760Dy ideal. At present, experiments are also near the double half-shell nuclear 16760Dy halo conversion spectrum
