| The nuclear radius is the fundamental parameter used to describe the structure as well as the effective interactions of atomic nucleus. Any improvement to its measurements or the techniques applied could be a milestone to the understanding of nuclear structure and its complex dynamics. There is a great challenge from both theoretical and experimental measurement of nuclear radius that the range of nuclear force is far from being constant, especially when there is a significant difference between proton and neutron numbers. Attempt to tackled with this challenge have been made especially, to improve the A – dependence formula of measuring nuclear radius or to use another approaches that could provide constant R/A1/3 value. In view of these observations, this study, proposed a new approach to measure the nuclear size, from the study of the β+–decay and coulomb energy difference of finite-size nuclei. However, the study modeled nucleus as a positively charged object of charge +Ze equals in magnitude with negatively charged (-e) orbiting leptons, from which the nuclear potential charge radii, RC are measured. This measurement takes into account the interaction of leptons and successfully produced a simple formula that can be applied to measure the size of nuclear potential radius RC. The results are in good agreement with the previously measured values of RC using nuclear finite-size model. Therefore, the present study improves the validity of previously measured RC. For the improved nuclear finite-size model, the studies could provide more information on the understanding of nuclear matter and charge radius, nuclear potential, charge distributions, coulomb energy, electron energy levels and on their future measurements. |
