Measurement of Gamow-Teller strength for [Formula Presented] as a solar neutrino detector

Gamow-Teller transition strengths obtained in the [Formula Presented] reaction studied at 94, 159, and 197 MeV incident proton energies are presented, and used to evaluate the efficiency of [Formula Presented] as a solar neutrino detector. Excitation of the [Formula Presented] first excited state at [Formula Presented] in [Formula Presented] sensitive to [Formula Presented] 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 [Formula Presented] the excitation energy of the isobaric analog state, and the centroid of the Gamow-Teller resonance in [Formula Presented] © 1999 The American Physical Society.
