【摘要】：对称性在了解诸如原子核的转动、自旋和宇称、及同位旋等核结构性质中都起着重要的作用,并且使复杂的原子核结构问题得以简化。辛弱数就是由于原子核的对相互作用中的对称性所导出的众所周知的好量子数。通过对丰中子和缺中子核素及核素的高自旋态的衰变数据分析来揭示辛弱数的近似守恒性质。研究结果表明,在准幻核的高自旋同质异能素链中,无论所涉及的价空间的核子轨道有何不同,广义辛弱数总是近似的好量子数。
[Abstract]:Symmetry plays an important role in understanding the properties of nuclear structures such as nucleus rotation, spin and parity, and isospin. The symplectic weak number is a well-known good quantum number derived from the symmetry of the pair interaction of the nucleus. The decay data of spin states are analyzed to reveal the approximate conservation properties of symplectic weak numbers. The generalized symplectic weak numbers are always approximate good quantum numbers in the chain of high spin isomorphic isokines of quasi-phantom nuclei, regardless of the difference of the nucleon orbits in the valence space involved.
