Some Effects on A Single Particle Energies

With the phenomenological A-nucleus potentials of Woods-Saxon shape,the effects of the maas-number dependence of the shrinkage,the effective mass m*^ and the charge-symmetry breaking (CSB) on the single particle energies are discussed.It is found that the single particle energies are not sensitive to the effective mass m*^.But the radius parameter depended on the mass number (ro (Ac) = r1 + r2A-2/3) can substantially improve the results.We also found that CSB effect is significant for heavy hypernuclei with a large neutron excess.

重子内部存在类似分子的结构

人们普遍认为重子由三个夸克组成。然而,处于激发态的Λ（1405）粒子或许会挑战这一简单的描述：Λ粒子在这一激发态表现得像是由一个夸克二重态（即夸克对）和一个夸克三重态构成的＂分子＂。
