Inelastic electron scattering form factors for fp-shell nuclei 42Ca, 44Ca, 46Ti,
48Ti, 50Cr and 54Fe are investigated taking into account higher energy configurations outside the fp-shell. Higher energy configurations, which are called core polarization (CP) effects, are included through a microscopic theory that includes excitations from the core 1s-1p, 2s-1d orbits and also from 2p-1f shell to the higher allowed orbits with 6~! excitations. The calculations are performed in the FP model space by employing GXPF1 and FPD6 effective interactions while the core polarization are calculated with Skyrme-Hartree Fock (Skx) and harmonic oscillator (HO) as residual interactions. The predicated total form factors are compared with the available experimental data and it is shown that the inclusion of the higher excited configuration are very essential in both the transition strength and momentum transfer dependence to obtain reasonable description of the data with no adjustable parameters.
