Cross-sections of bound-free I2(0g+, 1g(aa, ab) ←hvf B0u+, vB=18-21) and bound-bound I2(0g+, 1u(bb) ←hvf B0u+, vB=21, JB) transitions at a fundamental harmonic of the Nd:YAG laser

Bound-free electric dipole allowed I-2(a1(g), a' 0(g)(+)(aa), 0(g)(+), c1(g), c' 1(g)(ab) <- hv(f)(i) B0(u)(+), v(B) = 18 - 21, J(B)) and bound-bound electric dipole allowed I-2(0(g)(+) (bb) <- hv(f)(i) B0(u)(+), v(B), J(B)) and electric dipole forbidden I-2(1(u)(bb) <- hv(f)(i) B0(u)(+), v(B), J(B)) transitions at a fundamental harmonic of the Nd: YAG laser, h. i f, have been studied. Excitation spectra of the I-2 (B, v(B), J(B) -> X, v(X) = 1, J(X)) luminescence from the B, v(B) = 18, 20, 21, J(B) rovibronic states have been measured with switched on and switched off h. i f generation. Temporal behaviors of the luminescence intensities from these states with switched on and switched off hv(f)(i) generation have also been measured. These data allow us to determine or estimate cross-sections of the electric dipole allowed and electric dipole forbidden transitions under study. Dipole moment of the I-2(0(g)(+) (bb), v(0) = 7 <- hv(f)(i) B0(u)(+), v(B), J(B)) transition has also been determined.
