The elastic scattering of polarized 3He by 2H at 22.5, 24, 27, 30 and 33 MeV Original Research Article

The angular distributions of the analysing power and the relative cross-sections for the elastic scattering of polarized View the MathML source nuclei by View the MathML source have been measured at incident View the MathML source energies of 22.5, 24, 27, 30 and 33 MeV. The data, considered in terms of fitted Legendre polynomials, clearly show a structure near 30 MeV View the MathML source energy which is more striking for odd L coefficients. In addition, our data, along with other data on the differential cross sections and on the analysing power for the scattering of polarized View the MathML source, have been analysed for the phase shifts and mixing parameters in the S-matrix description. The phase shifts selected are compared with those from resonating-group theory calculations. The prominent residual differences were attributed to further resonances which involve the formation of View the MathML source nuclei at high excitation energy. Finally a level scheme is compared with the predictions of a multi-particle, multi-shell model calculation.
