用γ射线装置测量了{sup 252}Cf自发裂变中的高倍数瞬发γ射线符合事件，扩展了{sup 102}Zr的能级图。先前的身份已得到确认。一个两个准粒子带的带头能量为2926.4 keV已被确定为第一次，以及两个旋转集体带，带头能量分别为1386.3和1652.7 keV。自旋和政党的基础上分配的水平系统和角度相关测量。
The level scheme of {sup 102}Zr has been expanded by measuring high-fold prompt {gamma}-ray coincidence events in the spontaneous fission of {sup 252}Cf with the Gammasphere array. Previous identifications have been confirmed. A two-quasi-particle band with a band head energy of 2926.4 keV has been identified for the first time, as well as two rotational collective bands, with band head energies of 1386.3 and 1652.7 keV, respectively. Spins and parties are assigned based on level systematics and angular correlation measurements.
