Abstract: (APS)
Neutron and proton spectral functions of Ar40, Ca40, and Ti48 isotopes are computed using the ab initio self-consistent Green's function approach. The resulting radii and charge distributions are in good agreement with available experimental data. The spectral functions of Ar and Ti are then utilized to calculate inclusive (e,e′) cross sections within a factorization scheme and are found to correctly reproduce the recent Jefferson Lab measurements. Based on these successful agreements, the weak charged and neutral current double-differential cross sections for neutrino-Ar40 scattering are predicted in the quasielastic region. Results obtained by replacing the (experimentally inaccessible) neutron spectral distribution of Ar40 with the (experimentally accessible) proton distribution of Ti48 are compared and the accuracy of this approximation is assessed.
