Abstract

Angular distributions for pion single charge exchange to the isobaric analog state were measured for K39 and Ca48 at T=48 MeV. The cross sections on K39 and Ca48 exhibit a less deep minimum at zero degrees than was seen previously on N15. The large-angle K39 cross sections are roughly equal to those for N15, while the 0°to 60°Ca48 cross sections are approximately four times larger. The extrapolated zero-degree center-of-mass cross sections are 2.71.0 b/sr for N15, 125 b/sr for K39, and 11025 b/sr for Ca48, and the angle-integrated cross section for K39 is 55765 b. The large back-angle cross sections for K39 are attributed to strong quadrupole contributions to the isobaric analog state transition.
