在 226Ra 靶上的非弹性氘核散射中观察到了集体态。在 90°、125° 和 140° 的散射角下测量光谱。在磁谱仪中分析反应产物并在照相乳液中检测。发现 226Ra 中的 2+ 强度高度分散。在 320 和 1119 keV 下为分配的 3− 态推导的跃迁强度与 226Ra 的振动和静态八极变形模型描述兼容。
Collective states have been observed in inelastic deuteron scattering on a target of 226Ra. Spectra were measured at scattering angles of 90°, 125° and 140°. The reaction products were analyzed in a magnetic spectrograph and detected in photographic emulsions. The 2+ strength is found to be highly fragmented in 226Ra. The transition strengths deduced for the assigned 3− states at 320 and 1119 keV are compatible with both a vibrational and static octupole deformed model description for 226Ra.
