【Abstract】 This paper constructed a theoretical model for a four_identical_boson system. With this model and few_body methods, we calculated the energy spectra of low_lying states L π i(L=0,1,2,π=±1,i=1,2) for a four α particle system. What′s more, the origin of the structural characters of low_lying states of nucleus 16 O has been uncovered, therefore the law of classifying the low_lying states of nucleus 16 O has been found by investigating the decisive effect of quantum mechanics symmetries on the system.更多还原
