英文摘要: The effective A-nucleon interaction in single A hypernuclei is studied using the Relativistic Mean Field theory. Five sets of hyperon-meson coupling parameters, for Lambda - sigma and Lambda - omega interactions, are obtained by fitting the recent data of the binding energy of a Lambda in the 1s state of C-13(Lambda), B-Lambda(1s1/2). The detailed method is to fix one of the parameters to be a special value such as 2/3 or 1 or to suppose two of them be equal, and then the parameter sets are deduced. With these parameter sets determined from only this experimental quantity,we calculate the single-particle spectra of Lambda in single-Lambda hypernuclei for a wide range of mass number from A = 9 to A = 208. The calculations reproduce the available data well.
