Polarized neutron capture onHe3atEn=9.0MeV

A polarized neutron beam has been used to measure the angular distribution of the analyzing power for the /sup 3/He(n,..gamma..)/sup 4/He reaction at E/sub n/(E/sub x/) = 9.0 (27.3) MeV. The angular distribution of the cross section, obtained with an unpolarized beam, is combined with these data to obtain the b/sub k/ coefficients. These coefficients are compared to the results of a previous measurement performed for the /sup 3/H(p,..gamma..)/sup 4/He reaction, and to the results of a recent continuum shell model calculation.
