The elastic and inelastic longitudinal electron scattering form factors in of chromium isotopes (^50,52Cr) isotopes were studied using the radial wave functions of a transformed harmonic oscillator potential in the local scale transformation technique. Occupation numbers from configuration mixing using the Hsieh-Wildenthal (HW) method for ^50,52Cr were considered in parallel with those obtained using the adjusted occupation numbers. For shell interactions, the model space for HW interaction is restricted to the 1d3/2 and 1f7/2 subshells. The charge density distributions in the ground state and differential electron scattering cross-sections were computed. The inelastic form factors were studied by including core polarization using the Bohr-Mottelson model. For ⁵⁰Cr, the three C2 transitions and the two C4 transitions were investigated. For ⁵²Cr, the inelastic form factor for the two C2 transitions and for the two C4 transitions is investigated. In general, the use of the transformed harmonic-oscillator (THO) basis proved itself to be a good candidate to study stable nuclei, where good results (elastic and inelastic Coulomb form factors and differential cross sections) were obtained for ^50,52Cr isotopes.
