Abstract

The cross section and transverse tensor analyzing power T20T have been measured in kinematically complete geometry for the (d4,pα)n reaction at 7 MeV. Kinematic conditions were chosen to correspond to production of the singlet deuteron (d*) near a c.m. angle of 100°. The data show clear evidence for production of the d*. 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* is produced, but this agreement worsens as the region in which Enp=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-α Coulomb interaction, but the magnitude of the cross section is underpredicted in this calculation.
