摘要:

利用三轴转子模型(TRM)和非谐振子(AHV)框架下的声子组态混合方案,解析地建立了核$2^+_1$和$2^+_2$态电磁性质之间的一系列整体关联.这两个模型的关联式都能粗略地描述四极集体的实验数据。此外,似乎有一个强大的正交变换之间的AHV和TRM基地的现实核系统,这表明这两个模型实际上可能是描述集体的特点,核低躺在类似的模型空间。

英文摘要:

By using the general triaxial rotor model (TRM) and the phonon-configuration mixing scheme within an anharmonic-vibrator(AHV) framework, a series of global correlations between electromagnetic properties of nuclear $2^+_1$ and $2^+_2$ states are analytically established. The correlations from both models can roughly describe the experimental data involving quadrupole collectivity with few exceptions. Furthermore, there seems to be a robust orthogonal transformation between the AHV and TRM bases for realistic nuclear systems, suggesting that the two models may in fact be describing the collective features of nuclear low-lying states in similar model spaces.
