Program for calculations of
the vibrational excitation and dissociative electron attachment cross sections
within the nonlocal resonance model for hydrogen molecule: time-independent approach

Description

The program NRM_For_H2_Coupled_Time_Indep_DiffEqs solves the nuclear dynamics of the electron collisions with the hydrogen molecule within nonlocal resonance model and calculates the vibrational excitation and dissociative attachment cross sections. The time-independent approach is used and the numerical grid method introduced by T.N. Rescigno and C.W. McCurdy [1, 2] is employed. The cross sections are needed for applications in molecular and plasma physics.
