## Abstract

Quasielastic [Formula Presented] reactions on [Formula Presented]- and [Formula Presented]-shell nuclei 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 13 [Formula Presented] target nuclei ranging [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented] and [Formula Presented] Pure [Formula Presented] Fermi-type transitions were observed in six of them. As for the other seven nuclei, contributions from mixed [Formula Presented] components or those from unresolved transitions 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 a total of 13 [Formula Presented] angular distributions was fitted by macroscopic DWBA calculations with a Lane-model optical potential to derive systematically the isovector part of the potential. The best-fit parameters for each target are presented. [Formula Presented]-dependent global parameters were obtained from these best-fit parameters by a least-squares fit.
