Energy for photodisintegration of deuterium?

[Arun S. Johnson]

Is there a logical method to calculate the energy of a photon that would be needed for photodisintegratio? Could one simply use the difference in binding energy between the initial atom and products, are there more factors that need to be considered, can it only be determined experimentally? If the case is that there is no simple way to determine energy for photodisintegration, would someone be kind enough to point me towards a table of photodisintegration values, or simply the value for deuterium? Many thanks!

The difference in binding energy gives you the absolute minimum. The cross-section could be small very close to the threshold.
