The angular and energy distribution of the ionic products from the reaction of B+in its first excited state,3Pu, with molecular deuterium was studied over a projectile energy range of 1 to 40 eV in the laboratory system. The product states as determined from the limiting values of the translational exoergicity were BD+thinsp; (2Sgr;+) and BD+thinsp; (2Pgr;). The experimental velocity contour maps indicated that BD+(2Sgr;+) was arising through complex formation whereas BD+thinsp; (2Pgr;) was proceeding by a direct mechanism.
