Abstract
Angular distributions of MI (M=Ca, Sr, or Ba) products scattered from crossed beams of HI and M are reported and compared with derived expressions for the angular distributions of the velocities of the center‐of‐mass. These comparisons indicate that the reaction threshold relative kinetic energies, E*, are 5, 4, and 2.5 kcal/mole for the Ca, Sr, and reactions, respectively. Energy conservation and these measured E* values establish rigorous lower bounds for of 64 (CaI), 65 (SrI), and 66 (BaI) kcal/mole.
