The magnetic moments and electric quadrupole moments of the B-5 isotopes were calculated using different nuclear interactions and sets of effective charges. Instead of relying on core polarization, the effective charges were adopted through a microscopic theoretical approach. The one-body density matrix (OBDM) elements for these isotopes were calculated using the NuShellX@MSU code. The calculations were carried out within the shell model framework, using both the p- and psd-model spaces (MS). These model spaces were selected for nuclei with proton number Z = 5 and neutron number N > 3. The theoretical results for magnetic and quadrupole moments were compared with available experimental data. Theoretical magnetic moments of the B-8,B-10,B-11,B-12,B-13 isotopes showed good agreement with experiment when using the p-MS with the pwt interaction, and the psd-MS with the psdmwk interaction. Similarly, the theoretical electric quadrupole moments reasonably well with the experimental values when using the p-MS with the pkuo interaction, and the psd-MS with the psdmwk interaction.
