Calculation of the nuclear transition charge density in a microscopic sdgIBM-1

Formulae of proton and neutron boson structure functions (BSF's) are deduce d in terms of a microscopic approach of sdgIBM (namely, microscopic sdgIBM) . For the nucleus Os-190, the value of BSF's is worked out. Due to the high similarity, the maximum F-spin truncation is made under the full-symmetry approximation. Thereafter, calculations of E2 and E4 transition charge dens ities (TCD's) are performed in the sdgIBM-1. It is found that the E2 and E4 TCD's can be reproduced quite satisfactorily in the uniform frame of micro scopic sdgIBM-1.
