States in 40Ca near 12 MeV Excitation from the 39K(p, g)40Ca Reaction

Abstract

Measurements of the 39K(p, ytOCa reaction in the region near 12 MeV show that none of the four resonances observed between 12·03 and 12·09 MeV excitation energy in 40Ca has In = 0+. If one of these states corresponds to the fj.f = 0 transition seen in the high energy (p, p') reaction at an excitation energy of 12·06±0·02 MeV, this suggests that the spin and parity of this state are 1 +.
