N2 - Quasielastic (p, n) reactions were studied at an incident proton energy of 35 MeV. Differential cross sections for isobaric analog [Formula Presented] (Fermi-type) transitions and their angular distributions were measured in 27 [Formula Presented] target nuclei [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented] and [Formula Presented] Pure [Formula Presented] Fermi-type transitions were observed in 23 of them. As for the four light odd-A nuclei, contributions from mixed [Formula Presented] components were evaluated by microscopic distorted-wave Born approximation (DWBA) calculations to subtract them from the raw data and extract pure Fermi-type transition strengths. Thus 27 [Formula Presented] angular distributions were obtained, and fitted by macroscopic DWBA calculations with the Lane-model optical potential to derive systematically the isovector part of the potential. The best-fit parameters for each target are presented. The present results combined with our previous analysis on 13 other nuclei in the [Formula Presented] region cover almost the entire mass region. They were used to obtain A-dependent global parameters by least-squares fit.
