Abstract :
A model is provided to deal with the competition between the [1 + 1] dissociation channel via H ∼ ← B ∼ 2 Σ u + ( 0 0 0 , 1 0 0 ) ← X ∼ 2 Π g, 3 / 2 ( 0 0 0 ) transitions and the [1 + 1′] dissociation channel via the C ∼ 2 Σ g + ( 0 0 0 , 1 0 0 ) ← B ∼ 2 Σ u + ( 0 0 0 , 1 0 0 ) ← X ∼ 2 Π g, 3 / 2 ( 0 0 0 ) transitions for CS 2 + ions. The dependence of the product branching ratios R = [S+]/[CS+] on the intensity ratios RI = I2/I1 of two dissociation lasers was measured. By fitting the RI–R data with the theoretical formula the excitation cross section ratios of Rσ(0 0 0) = σC(0 0 0)/σH(0 0 0) = 0.55 ± 0.07 and Rσ(1 0 0) = σC(1 0 0)/σH(1 0 0) = 0.43 ± 0.04 have been obtained for the competitions between C ∼ ( 0 0 0 ) ← B ∼ ( 0 0 0 ) and H ∼ ← B ∼ ( 0 0 0 ) transitions, and between C ∼ ( 1 0 0 ) ← B ∼ ( 1 0 0 ) and H ∼ ← B ∼ ( 1 0 0 ) transitions, respectively.
