英文摘要dissociation dynamics of cs2+ vibrationally mediated via its (b) over tilde (2)sigma(+)(u) state, was studied using the time-sliced velocity map imaging technique. the parent cs2+ cation was prepared in its (x) over tilde (2)pi(g) ground state through a [3 + 1] resonance enhanced multiphoton ionization process, via the 4p sigma(3)pi(u) intermediate rydberg state of neutral cs2 molecule at 483.14 nm. cs2+ ( (x) over tilde (2)pi(g)) was dissociated by a [1 + 1] photoexcitation mediated via the vibrationally selected (b) over tilde state over a wavelength range of 267 -283 nm. at these wavelengths the (c) over tilde (2)sigma(+)(g) and (d) over tilde (2)sigma(+)(u) states are excited, followed by numerous s+ and cs+ dissociation channels. the s+ channels specified as three distinct regions were shown with vibrationally resolved structures, in contrast to the less-resolved structures being presented in the cs+ channels. the average translational energy releases were obtained, and the s+/cs+ branching ratios with mode specificity were measured. two types of dissociation mechanisms are proposed. one mechanism is the direct coupling of the (c) over tilde and (d) over tilde states with the repulsive satellite states leading to the fast photofragmentation. the other mechanism is the internal conversion of the (c) over tilde and (d) over tilde states to the (b) over tilde state, followed by the slow fragmentation occurred via the coupling with the repulsive satellite states.
