近年来,在A～110核区寻找基于πg9/2νh11/2组态(质子费米面位于πg9/2子壳的上部,中子费米面位于vh11/2子壳的底部)的手征双重带成为原子核高自旋态研究的热点。2004年,C.Vaman等[1]在该核区的104Rh中找到了第1例手征双重带。随后,孟杰等[2]预言,在Rh、Ag和In等同位素奇-奇核中都可能存在手征对称性现象。因此在A～110开展原子核的手征性研究,对原子核自发转动对称性破缺认识以及理论模型的检验有重要的意义。 In recent years, looking for chiral doublets based on the πg9 / 2νh11 / 2 configuration (the proton Fermi surface is located in the upper part of the πg9 / 2 husk and the neutron Fermi surface is located at the bottom of the vh11 / 2 husk) The band becomes a hot spot in the study of high spin states of nuclei. In 2004, C. Vaman et al. [1] found the first chiral double band in 104Rh in the nuclear region. Subsequently, Meng et al. [2] predicted that there may be chiral symmetry phenomena in isotopic odd-odd nuclei such as Rh, Ag and In. Therefore, carrying out the chiral study of nuclei in A ~ 110 is of great significance to the understanding of the breakage of the spontaneous rotational symmetry of the nucleus and the test of the theoretical model.
