在 /sup 40/Ar 诱导反应导致 /sup 122/Te、/sup 150/Gd 和 /sup 164/Er 系统之后，已观察到 2--30-MeV 范围内的 ..gamma.. 射线光谱。 E/sub ..gamma../>10 MeV 光谱中的肩部被解释为由巨偶极子共振产生，并且与使用巨偶极子共振强度函数的统计模型计算一致。他们的观察提供了研究核形状和动力学作为温度和自旋函数的可能性。
Spectra of ..gamma.. rays in the 2--30-MeV range have been observed following /sup 40/Ar-induced reactions leading to the /sup 122/Te, /sup 150/Gd, and /sup 164/Er systems. Shoulders in the spectra for E/sub ..gamma../>10 MeV are interpreted as arising from the giant dipole resonance and are consistent with statistical-model calculations using the giant-dipole-resonance strength function. Their observation offers the possibility of studying nuclear shapes and dynamics as functions of temperature and spin.
