RELATIVISTIC MICROSCOPIC OPTICAL POTENTIALS FOR NUCLEON-NUCLEUS IN THE IMPROVED LOCAL DENSITY APPROXIMATION
以改进的定域密度近似研究核子-有限核的相对论微观光学势

Based on Walecka model, the refativistic microscopic optical potentials (RMOP) for nu-cleon-nucleus are investigated in the improved local density approximation (ILDA). The RMOP in ILDA, which include the effect of interaction range, are obtained by folding RMOP in LDA with Gaussian form factors. The parameters in Gaussian form factors are adjusted to fit the empirical values of the volume integral and root mean squar radius of the optical potential for p-Ca. By analysing the elastic scattering of proton from nuclei, we get a better agreement of ILDA with experiment data than that of LDA.
