Abstract
Quantum-mechanical calculations of the electronic states of a triatomic excimer of hydrogen are used to estimate the parameters of the photodissociative transition from the lowest bound state of H3 * into the ground state. The estimates obtained agree with the characteristics of the emission spectra of a laser spark in dense hydrogen. The cross section for the photodissociation of H3 * is small. It is also established that the terms of the combining states cross near the minimum of the bound-state energy. It is concluded that the feasibility of gain on this transition is problematic.
