The analyzing power for the 2H(d, n)3Heg.s. reaction from 5.5 to 11.5 MeV

The analyzing power A y ( θ ) for the 2 H(d, n) 3 He g.s. , reaction was measured from 0° to about 150° (c.m.) at 5.5, 7.0, 8.5, 10.0 and 11.5 MeV. The experiment was conducted with a newly developed pulsing and bunching system for the polarized deuteron beam and used standard time-of-flight neutron detection. The present results disagree in some angular regions with measurements of the same observable reported recently by a Zurich group who detected the 3 He particles, but agree with the limited angular distribution measured at 10 MeV by Hilscher and Liers, who also detected 3 He particles. The present results are reported in terms of associated Legendre polynomial expansions of the product σ ( θ ) A y ( θ ).
