摘要：利用3台迷你橙色转换电子能谱仪和4台Euroball Ge Cluster探测器对超变形135Nd进行了γ-e -符合谱分析。超变形带内的跃迁具有预期的E2多极性。766.5 kev跃迁将带连接到正宇称态，其转换系数与M1多极相一致。由此导出了超变形带的正宇称。没有发现E0转换的证据。
Abstract: Three mini-orange conversion–electron spectrometers and four Euroball Ge Cluster detectors have been used for γ–e- coincidence spectroscopy of superdeformed 135Nd. Transitions within the superdeformed band are shown to have the expected E2 multipolarity. The 766.5–keV transition which links the band to a positive-parity state has a conversion coefficient consistent with M1 multipolarity. Consequently, positive parity is deduced for the superdeformed band. No evidence for E0 transitions was found.
