Abstract: | The differential cross section, the vector- and the tensor-analyzing powers of the reaction 2H(, p)3H have been measured. The polarization data were obtained at 11 energies between 1.0 and 13 MeV at lab angles between 5° and 160°. The data were fitted with Legendre polynomials and the resulting coefficients analyzed for resonances in 4He. Overwhelming evidence for a 1? level at 24.1 MeV and a strong indication of a 4+ level at 24.6 MeV excitation energy have been found. |
