摘要In terms of the YN interaction based on the chiral SU(3) quark model, the spectra of light hypernuclei H-4(Lambda), He-4(Lambda) and He-5(Lambda) are calculated. The result shows that the effective local AN potential, as an approximation, cannot offer a reasonable explanation of the empirical data, while the non-local AN potential, also as an approximation, can provide a reasonable range of the binding energy of He-5(Lambda) and correct ordering of the energy levers of H-4(Lambda), He-4(Lambda). This indicates that the non-local character of the effective YN interaction plays an important role in binding behavior. The upper bounds and lower bounds of energy levels are given by employing two sets of model parameters in the calculation. Thus, the experimental data of hypernuclei can provide more information as the constraints of model. In the present stage, YN interaction(no matter phenomenology of theoretical interaction) cannot be finalized due to lack of experimental data. Utilizing experimental data, it is possible to optimize model parameters in the theoretical studies of YN interaction.
