摘要
The photoassociation spectrum of an equilibrium vapor of mercury atoms in the range of 34960-37250 cm(-1) is recorded with the help of a tunable laser in observations of laser-induced fluorescence. The Franck-Condon structure, i.e., periodic variations in absorption intensity against a continuous background, is observed. The structure makes it possible to determine spectroscopic parameters of the upper attractive potential and the lower repulsive potential including that with a van der Waals well. The absorption spectrum of collisional pairs of mercury atoms is calculated using the Numerov-Cooley procedure for integrating the Schrodinger equation. Potential curves of the upper and lower states Hg-2(D1(u)) and Hg-2(X0(g)(+)) are determined by comparing the calculated spectra with the experimental one. (C) 2001 MAIK "Nauka/Interperiodica".
