Abstract
The theory of the reaction is reviewed with emphasis on the dominant, or (), mode. The differences between the length and the gradient electric dipole operators are studied in detail and the two-photon cross section () is calculated using both operators. The length operator yields a very reliable value of μb (± 1%). The result obtained with the gradient operator is ∼20% smaller and has large uncertainties. Results for other two-photon modes are also presented.
