原子核是一个复杂的多体系统,具有多核子共同作用的显著集体涌现性质。玻尔和莫特尔森[1]根据几何形状以及围绕这些形状的叠加振荡描述了原子核中的集体运动。后来,李代数和对称性被用来描述核动力学[2],随后壳模型方法[3]的进步与新的有效核子-核子二体和三体相互作用,以及最近的Hartree-Fock-Bogoliubov近似在扩展的生成坐标方法[4]。然而,基本的科学问题仍然是一样的。在原子核中,基态有明显的形变,”低的0+态是建立在基态上的集体振动,还是它们是共存形状的最小值?“Ref. [4]已经表明,对于相当大比例的K= 0+激发,建立在变形基态(gs)上,事实上应该是集体振动。由于具有足够令人信服的寿命、转移反应横截面和E0跃迁的实验数据,这个问题仍然悬而未决[5]。本文综述了有关0+态寿命的实验情况。
The nucleus is a complex many-body system with some remarkable emergent collective properties of multiple nucleons acting together. Bohr and Mottelson [1] provided a description of collective motion in nuclei based on geometrical shapes with superimposed oscillations around those shapes. Later, Lie algebras and symmetries were used to describe nuclear dynamics [2], followed by advances in the shell model approach [3] with new effective nucleon-nucleon two-and three-body interactions, and more recently with Hartree-Fock-Bogoliubov approximations within the extended generator coordinate method [4]. Yet, the underlying science question has remained the same. In nuclei, where there is explicit deformation in the ground state," are the low-lying 0+ states collective vibrations built on the ground state or are they minima of a coexisting shape?" Ref.[4] has shown that for a significant percentage of K= 0+ excitations built on the deformed ground state (gs) should, in fact, be a collective vibration. The question has remained open due to sufficiently convincing experimental data with lifetimes, transfer reaction cross sections, and E0 transitions [5]. This paper summarizes the experimental situation regarding the lifetimes of 0+ states.
