The cross section and transverse tensor analyzing power /sup T/T/sub 20/ have been measured in kinematically complete geometry for the /sup 4/He(d,p..cap alpha..)n reaction at 7 MeV. Kinematic conditions were chosen to correspond to production of the singlet deuteron (d/sup */) near a c.m. angle of 100/sup 0/. The data show clear evidence for production of the d/sup */. A comparison of the measured cross sections and analyzing powers with the results of three-body calculations shows good agreement in the kinematic region away from that in which the d/sup */ is produced, but this agreement worsens as the region in which E/sub n//sub p/ = 0 is approached. In this region, the data are reproduced qualitatively by a calculation which includes the singlet n-p interaction as well as an improved approximation to the p-..cap alpha.. Coulomb interaction, but the magnitude of the cross section is underpredicted in this calculation.
