Abstract
The excitation of 1+ states by inelastic scattering of 201 Me V protons, studied previously on the N = 28 nuclei 48Ca and 51V, has been pursued on 50Ti, 52Cr and 54Fe; for the three latter nuclei, many sharp states are observed which have a very forward-peaked angular distribution characteristic of a ΔL = 0 transition. The results agree reasonably well with (e, e') measurements. A comparison with (γ−1, γ) results demonstrated the 1+ nature of these states. The data are compared with DWIA calculations performed using the shell-model wave functions of Metsch and Knüpfer. This comparison indicates that he isoscalar excitations are probably weaker than predicted. The ratio of experimental to predicted cross sections ranges from 0.25 for 50Ti to 0.44 for 54Fe.
