THE EFFECT OF TWO-BODY SHORT RANGE CORRELATION FUNCTIONS ON THE CHARGE DENSITY DISTRIBUTIONS OF SOME LIGHT NUCLEI

Abstract

The effects of short range correlation are taken into account in an effective way, that is, expressing the ground state wave function in terms of the occupation probabilites of singl particle orbits for various closed and open shell nuclei with N=Z. The effect of the SRC's and the occupation probability ( ) of higher states on the ground state 2BCDD's and the root mean square charge radii are investigated. It is found that the inclusion of SRC's leads to enhance the probability of transferring the protons from the central region of the nucleus towards its surface since this causes to reduce the central part of the 2BCDD's significantly and increases the tail part of them slightly and consequently leads to increase the calculated values of for 4He, 12C, 16O, 28Si, 32S and 40Ca nuclei. Considering the effect of higher occupation probabilities and the effect of SRC's are important in getting good agreement between the calculated 2BCDD's.
