Giant dipole state in the deuteron in simple models

By assuming a Serber interaction and either asymptotic or Hulthen wave functions for the deuteron, we can easily obtain the mean energy of the dipole state of the deuteron. We do this in two ways: first, we construct the dipole state as a bound state in the continuum and, secondly, we use the photodisintegration cross section. The results for the bound state calculation agree with the continuum calculation.
