Abstract
The mean excitation energy (the Bethe logarithm) is calculated for the lowest rotational (up to ) and vibrational (up to ) states of the hydrogen molecular ion . The calculations are based on a method of the direct integration over photon momenta. The estimated accuracy of obtained values is about six significant digits.
