The general formulae for the nucleons magnetic moments are obtained by a straightforward calculation and the relative weights between different quark components in the static wavefunctions of nucleons are estimated. 重子 夸克模型 核子 baryon quarkmodel nucleon O572.2 国家自然科学基金(61672102) 1998-01-01 2021-04-01 1
