Abstract

The velocity and angular distributions of Mg+(2P3/2) produced by photolysis of Mg+-Ar complex at 4.66 eV were observed using an apparatus set up for imaging fragment ions from mass-selected ions. The translational energy Et and the anisotropy parameter β were measured to be 640 ± 80 cm-1 and 1.03 ± 0.05, respectively. The binding energy of Mg+-Ar in the ground state, estimated to be 1180 ± 80 cm-1, agreed with those reported in the literature. We have demonstrated that the recoil energy as small as 100 meV can be resolved using this apparatus.
