| Research Abstract |
An ion-imaging apparatus for cluster ions were developed by combining a time-of-flight mass spectrometer and a position-sensitive detector, in which temporal and spatial distributions were focused by two-stage acceleration. Ultraviolet photodissociation dynamics of MgAr^+ and Mg^+(ICH_3) cluster ions were recorded by employing laser ablation. As a result, excess energy partitioning and dynamical behavior were disclosed; for example, kinetic energy release in MgAr^+ upon 266 nm photodissociation was estimated to be604±100 cm^-1, anisotropic parameter β=0.98, and dissociation energy at the ground stateD0” = 1222±120 cm^-1.
