Abstract
An analysis is made of the feasibility of experimental investigation of the temperature dependence of the cross section of the 52P1/2 → 52P3/2 transition in the iodine atom in a photodissociation laser. The possibility of determination of the coefficient of the collisional broadening of the luminescence line emitted due to this transition, by dimer radicals (formed as a result of secondary chemical reactions in the active medium of the laser) and by iodine atoms, is also considered. It is shown how the temperature dependence of the cross section can be used to improve the precision of determination of the coefficients representing the collisional broadening of the luminescence line of the iodine atom by buffer gases and by iodides used as the starting materials in the iodine laser.
