The Quenching of Excited F( ~2P_(1/2)) and Cl(~2P_(1/2))Atoms by N~2(X~1___g~+ ) Molecules

摘要

The rate constant for the quenching of excited F(~2P_(1/2)) and Cl(~2P_(1/2)) atoms in collisions with N_2 mol ecules were calculated. The electron interaction matrix between N_2(X~1E+g ) and F and Cl atoms in the ~2P/_i state calculated asymptotically taking into account quadrupole-quadrupole, dispersion, and exchange interactions was used. The dynamic problem of electronic transitions was solved using the modified wave number approximation, the exactly solvable semiclassical exponential nonadiabatic bond model, and the method of phase functions.
