Abstract

In this paper, energy levels were calculated for two nuclei (14 8O6 , 14 6C8) by applying the nuclear shell model by using modified surface delta interaction (MSDI).The (MSDI) succeeded in energy levels calculation for the configuration (hole-hole ( ,this case facilitated the calculation of many holes outside closed shell by using the configuration (hole-hole). Computer programs were used to calculate important coefficients involved mainly in calculating energy levels include Clebch - Gordan , Racha coefficient and matrix element for two bodies by using modified surface delta interaction. Comparison the current values with the experimental values , it was found current values were in perfect agreement with the experimental values
