Transition rates and microscopic effective charges for 16C exotic nucleus


Quadrupole transitions and effective charges are calculated for 16C exotic nuclei with large basis no core shell model with truncations. Calculations with configuration mixing shell model with these limited model spaces usually underestimate the measured E2 transition strength. Instead of using constant effective charges, excitations out of major shell space are taken into account through a microscopic theory this is called core-polarization effects. The two body Michigan sum of three ranges Yukawa potential (M3Y) is used for the core-polarization matrix elements. The simple harmonic oscillator potential is used to generate the single particle matrix elements of 16C. The present calculations with core polarization (C. P.) effect reproduced the experimental data very well.
