The quadrupole collectivity and possible existence of macroscopic SU(3) symmetry in some collective shell model states

摘要: Abstract The shell model eigenfunctions for low-lying states of 56 Fe and 54 Cr are analyzed to illustrate that the “collective” these nuclei can be described as coupling a small number collective proton neutron groups. A truncation scheme doing calculations which would take advantage multipole collectivity is discussed. Finally, it suggested rotational features observed even in heavy deformed could consequence existence what might called an approximate “macroscopic” SU(3) symmetry.
