用核共振荧光(NRF)或核光子散射的方法研究了低激发态的电磁跃迁。利用激光逆康普顿散射产生的准单色线偏振光子束激发壳层闭合周围的原子核。本文介绍了对208PbNRF的测量结果。低于中子分离能的磁偶极子共振被分解为几个单独的跃迁。实验结果与基于自洽RPA计算的理论预测进行了比较。讨论了张量力的作用。
Low-lying electromagnetic transitions have been studied by the method of nuclear resonance fluorescence (NRF) or nuclear photon scattering. Quasi-monochromatic linearly polarized photon beams from inverse Compton scattering of laser light are used to excite nuclei around shell closure. In this report, the results of NRF measurements on 208Pb are presented. The magnetic dipole resonance below the neutron separation energy is resolved in to several individual transitions. The experimental results are compared with theoretical predictions based on self-consistent RPA calculations. A role of the tensor force is discussed.
