Photoionization of Excited H2 Molecules

Abstract

The photoionization cross sections of the singly excited H₂ states are calculated. The Coulomb approximation method utilizing the Temkin‐Vasavada electron ${\mathrm{H}}_2^{+}$ scattering phase shifts is used. Cross sections of $\sim \mathrm{1–2}{\text{× 10}}^{\text{−17}}\hspace{0.17em}{\mathrm{cm}}^2$ are found for all states at threshold, the same range as found for H(n=2) atoms.
