- Аннотация: Radiative lifetimes for 2 <= v’ <= 44 C-1 Sigma(+) state levels of NaRb and quenching collision cross-sections with Rb atoms have been directly measured in a thermal cell by detecting time resolved laser induced fluorescence after pulsed excitation. Many body multipartitioning theory was applied to calculate C-1 Sigma(+) - X-1 Sigma(+) and C-1 Sigma(+) - A(1)Sigma(+) transition dipole moments. The relevant ab initio matrix elements were converted to the C-1 Sigma(+) state radiative lifetimes. The strong spin-orbit A(1)Sigma(+) similar to b(3)Pi coupling effect on the total C-1 Sigma(+) transition probabilities and lifetimes of the C-1 Sigma(+) state is discussed. The measured radiative lifetimes show a decrease from 61 to 34 ns as the v’ values increase, the results being in good agreement with calculations. The averaged collisional quenching cross-section value sigma = (3 +/- 1) x 10(-14) cm(2) was determined for NaRb (C-1 Sigma(+)) + Rb collisions from the Stern-Volmer plots.
