摘要：

The emission continua of the dissociative transitions B (1) Sigma(u)(+)-X (1) Sigma(g)(+), B' (1) Sigma(u)(+)-X (1) Sigma(g)(+), C (1) Pi(u)-X (1) Sigma(g)(+), and D (1) Pi(u)-X (1) Sigma(g)(+) of molecular hydrogen have been calculated. Synthetic spectra of H-2 are in excellent agreement with high-resolution electron-impact-induced emission spectra obtained at 100 eV. An improved calibration standard is obtained, and the dissociation yields of the Lyman and Werner continua produced by electron-impact excitation are presented.
