Delbruck scattering is not associated with nuclear processes as far as I know. There is a related process called COMPTON scattering, which IS a nuclear-related process.
Delbruck scattering is the scattering of light by light, and its characteristic "box" diagram is one I've seen before. I will be editing to change the type of scattering. 24.84.67.65 05:11, 13 April 2007 (UTC)
Comments: The nucleus participates in the Delbrück scatterung process in two ways: (i) It provides the two virtual photons of the box diagram. The other two photons are real photons. (ii) It absorbes the recoil momentum transferred by the photons during the scattering process.

Observed or not?
editThere are some references claiming that light-by-light scattering has been observed. Perhaps we should update the lead section. Kismalac (talk) 08:48, 22 August 2013 (UTC)
Updated. I don't know what the correct format for citations is so I've linked directly to the relevant PRL article. 129.215.72.54 (talk) 12:08, 22 July 2015 (UTC)
Observed by R. Wilson - reference?
editIs this first observation by R. Wilson ever published? The best reference I could find is the report by H. Bethe (who is a very reliable source, of course) [1], but is there any official publication? Kkumer (talk) 13:33, 19 March 2024 (UTC)
