Angular distributions have been measured for inelastic scattering of 40 MeV protons to several states of 12C, 40Ca, 56Fe and 58Ni in the angular range of 4–20°. In a special small-angle scattering chamber, the inelastic protons were detected with a telescope consisting of three passing-geometry 3 mm Si(Li) detectors. Spurious events, produced when some of the very numerous elastic protons bombarding the detector produce nuclear reactions in it, were eliminated in a computer analysis. The experimental results are compared to DWBA and coupled-channel calculations, and to McCarthy's parity rule. |
