在RPA中计算了~（208）Pb、~（120）Sn、~（90）Zr和~（40）Ca的八极响应函数。大约60-70%的EWSR出现在能量为3 progol ω0的附近，分布在能量间隔为15 MeV的范围内。大约一半的强度（约30%）存在于一个单峰中。基于表面振动的激发，在核场论的框架内估计了这些态的宽度。它们被发现是6 MeV的顺序。结果似乎与最近的数据一致。
The octupole response function for208Pb,120Sn,90Zr and40Ca, is calculated in the RPA. Of the order of 60–70% of the EWSR is found around an energy of 3ħω0, spread over an energy interval of ∼ 15 MeV. About half of this strength (∼ 30%) lies in a single peak. Based on the excitation of surface vibrations, the widths of these states are estimated within the framework of the nuclear field theory. They are found to be of the order of 6 MeV. The results seem to be consistent with recent data.
