Gamow-Teller transition strengths obtained in the {sup 127}I(p,n){sup 127}Xe reaction studied at 94, 159, and 197 MeV incident proton energies are presented, and used to evaluate the efficiency of {sup 127}I as a solar neutrino detector. Excitation of the J{sup {pi}}=(3/2){sup +} first excited state at E{sub x}=0.125 MeV in {sup 127}Xe, sensitive to {sup 7}Be solar neutrinos, is evaluated. The sum of Gamow-Teller strength up to particle emission threshold and up to 20 MeV excitation energy are also reported. This paper also provides a new measurement of the Coulomb displacement energy {Delta}E{sub c}, the excitation energy of the isobaric analog state, and the centroid of the Gamow-Teller resonance in {sup 127}Xe. {copyright} {ital 1999} {ital The American Physical Society}
