Spectra of deexcitation γ-rays from 200 MeV π + on natural Cr and Ni targets were searched for indications of transitions in 52 Mn and 58, 60 Cu, respectively, produced by ( π + , π 0 ) charge exchange. Observed were weak transitions from the 52 Mn 2923 keV IAS, 52 Mn 870 keV state, 58 Cu 203 keV IAS, and a tentative transition from the 58 Cu 1428 keV state with cross sections of 3.7 ±1, 3.4±2, 3.1 ±3 and 3.4±3 mb, respectively. The peak at 870 keV may have arisen from a transition in 45 Sc rather than 52 Mn. |
