用（n，n（'）γ）反应研究了~（110）Cd的三声子结构。测量包括γ射线激发函数和角分布，并建议在110镉的三声子四极子态的寿命已使用多普勒频移衰减方法测量。此外，在2356 keV的110 Cd中，首次观察到三声子2（+）态衰减到两声子态。实验结果允许从三声子激发衰变的跃迁率的测定，并建立这些状态的集体性。实验B（E2）值进行比较，不同的理论描述。
The three-phonon structure of 110Cd has been studied with the (n, n(')gamma) reaction. The measurements consisted of gamma-ray excitation functions and angular distributions, and lifetimes of proposed three-phonon quadrupole states in 110Cd have been measured using the Doppler-shift attenuation method. Moreover, decay of the three-phonon 2(+) state in 110Cd at 2356 keV to a two-phonon state is observed for the first time. The experimental results allow the determination of transition rates of decays from the three-phonon excitations, and the collectivity of these states is established. The experimental B(E2) values are compared to different theoretical descriptions.
