利用iThemba实验室的高能量分辨质子非弹性散射，研究了稳定的偶数质量Nd同位素链中从球形到形变基态的等标巨四极共振（ISGQR）精细结构现象.变形的146，148，150 Nd同位素的背景扣除光谱的小波分析揭示了与使用SVmas10参数化从Skyrme RPA计算获得的尺度相对应的特征尺度。一个语义分析表明，这些尺度产生的能量转移之间的主要碎片的K= 0，1和K= 2的组件。
The phenomenon of fine structure of the Isoscalar Giant Quadrupole Resonance (ISGQR) has been studied with high energy-resolution proton inelastic scattering at iThemba LABS in the chain of stable even-mass Nd isotopes covering the transition from spherical to deformed ground states. A wavelet analysis of the background-subtracted spectra in the deformed 146, 148, 150 Nd isotopes reveals characteristic scales in correspondence with scales obtained from a Skyrme RPA calculation using the SVmas10 parameterization. A semblance analysis shows that these scales arise from the energy shift between the main fragments of the K= 0, 1 and K= 2 components.
