In this work . we applied the nuclear shell model by using Modified Surface Delta Interaction ( MSDI ) to study the nuclear structure for Ti42-44 nuclei from the calculation of the energy level values and its total angular momentum . After comperation with the experiment values which found to be rather in good agreement and determined the total angular momentum values of energy levels... https://www.roamingfreesims.com/product-category/ansell-downlights-fire-rated/
