利用{sup 235}U热中子裂变产生的质量分离放射性研究了{sup 102}Y的低自旋和高自旋异构体在高形变{sup 102}Zr中的衰变。基于单粒子和符合测量，导出了两种同分异构体的衰变方案.特别令人感兴趣的是在894和1211 keV处观察到的状态，它们分别被假设为0{sub 2}{sup +}和2{sub 2}{sup +}。这些新观察到的水平在{β}，{γ}，或球形带的可能的解释。
The decay of low- and high-spin isomers of {sup 102}Y to levels in highly deformed {sup 102}Zr was studied from mass-separated activity produced by thermal neutron fission of {sup 235}U. Based on {gamma} singles and coincidence measurements, decay schemes for both isomers are deduced. Of special interest are states observed at 894 and 1211 keV that are postulated to be 0{sub 2}{sup +} and 2{sub 2}{sup +}, respectively. Possible interpretations of these newly observed levels in terms of {beta}, {gamma}, or spherical bands are given.
