The root mean square value of nuclear charge radii is a parameter used for nuclear ground state analysis, however, its measurement is challenging because conventional fluorescence spectroscopy cannot be used. According to quantum mechanics, nuclear charge radii is observable obtained by using the system's wave function. However exotic magnesium nuclear system is a many-body problem because it consists of many particles, therefore the wave function cannot be obtained analytically. The many-body problem can be approximated by the Hartree-Fock method using Skyrme interaction as nuclear interaction model. Calculation using the HAFOMN program with ????, ????????, ????, ????????, ????????? , ????????, and ???????? as Skyrme parameter yields nuclear charge radii value near the reference value, with ????????? , ????????, and ???????? as the three best parameters. However, there are relatively large errors at ????= 31 and 32 because of the neglection of nuclear deformation.
