Reaction at 27 and 33 MeV

The analysing power (A) of the reaction \({}^2H({}^3\vec He,{}^4He){}^1H\) has been measured at 27 and 33 MeV, using the polarized 3He beam from the University of Birmingham Radial Ridge Cyclotron. In the experiment a (CD2)n solid target was used and the beam intensity on the target was 50 pA. To obtain the 27 MeV data an Al energy degrader was used. The statistical accuracy of the 33 MeV data is better than that of 27 MeV. The beam polarization was monitored by a 3He-proton polarimeter located after the target and was calibrated against the 3He + 4He double scattering results. The angular distributions of the analyzing power of the \({}^2H({}^3\vec He,{}^4He){}^1H\) reaction at 27 MeV and 33 MeV are shown in figs. 1 and 2 respectively.
