我们目前的结果停止束稀有同位素光谱调查在GSI（上升）实验的基础上检测的射线跃迁后thedecay的Pd。通过对Rh的实测低能级方案与壳层模型计算结果的比较，揭示了Rh的和轨道在解释结构特征中的重要作用。Gamow-Teller强度的低值可以归因于中子-质子相互作用的影响，这引起核态的资历混合增加，从而导致强度分裂到几个子能级。这些结果提供了进一步的强有力的迹象表明，Pd驻留在中间的结构过渡区的Pd同位素作为线接近。
We present results from stopped beam rare isotope spectroscopic investigations at the GSI (RISING) experiment based on the detection of-ray transitions following thedecay ofPd. A comparison between the measured low-lying level scheme ofRh and the prediction from shell-model calculations reveals the important roles of theandorbitals in explaining the structural features. The low values of the Gamow-Teller strengthscan be attributed to the influence of the neutron-proton interaction, which gives rise to an increased seniority mixing for the nuclear states, thereby leading to a fragmentation of the strength to several daughter levels. These results provide further strong indications thatPd resides in the middle of a structural transition region in the Pd isotopes as theline is approached.
