| Abstract: | In this work the deexcitation of the B3Π+(Ou+), v′ = 14 level of I2 after pulsed laser excitation has been studied. The quenching cross sections by collisions with I2, H2, CO, and CH4 have been measured. The experimental results are 190 ± 14, 2.5 ± 0.3, 15.1 ± 0.4, and 18.0 ± 0.6 Å2, respectively. These values are compatible (within 30%) with the semiempirical scaling law of proportionality with the product of polarizability and the square root of reduced mass. |
