摘要
研究了 A = 100-110 Mo 同位素随着 N 的增加而发生的急剧形状相变，这与结构的变形 N = 60 形状转折点有关。就形状随质子数 Z 的变化而言，Mo 同位素介于 Sr、Zr 和 Ru、Pd 同位素链之间。我们通过能级结构分析了这些 Mo 同位素的特殊光谱特征，包括基态带、Kπ = 2+ 和 Kπ = 4+ 激发带。这充分说明了三轴性与旋转带相关联的独特特征。相互作用玻色子模型（IBM-1）被用来重现钼同位素的能级结构。报告深入分析了钼同位素的光谱特征。重点是形状转变的物理学。
The sharp shape phase changes with increasing N of the A = 100–110 Mo isotopes, as associated with the deformed N = 60 shape turning point of the structure, are studied. In terms of the shape change with proton number Z, the Mo isotopes lie in between the Sr, Zr and Ru, Pd chain of isotopes. We have analyzed the special spectral features of these Mo isotopes through the energy level structures, in ground state bands, the Kπ = 2+ and Kπ = 4+ excited bands empirically. The unique features of the association of triaxiality, along with the rotational bands, are well illustrated. The interacting boson model (IBM-1) is used to reproduce the level structures of the Mo isotopes. An in-depth analysis of the spectral features of the Mo isotopes is presented. There is emphasis on the physics of the shape transitions.
