The expression of the two body term in the fac tor cluster expansion of the charge form factor of 40Ca is derived.lt contains the harmonic oscillator (HO) parameter bx and the parameter λ which originates from the Jastrow correlation function. This expression together with the corresponding one of 16O nucleus helps to find a mass dependence of λ and an approximate and fairly simple expres sion of the two body term of open shell nuclei in the region 16<A<40 which contains one free parameter, the HO parameter bi. The fitting to the corresponding experimental charge form factor is quite improved in comparison to the HO one without correlations.
