Fair use rationale for Image:Deap at snolab.JPG
[edit]
Image:Deap at snolab.JPG is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.
Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.
If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

How is the 128nm scintillation light produced
[edit]How is the 128nm scintillation light produced by the recoil of argon nucleus ? - Is it Cherenkov radiation, radioluminescence, or some form of photoluminescence ? - Rod57 (talk) 11:44, 29 August 2016 (UTC)
REPLY: Liquid argon scintillates when a charged particle (such as a recoiling argon nucleus with its electrons knocked off) loses energy and slows down inside of it. Energy from the slowing down particle is transferred to argon electrons which causes unstable dimers (Ar2 molecules) to form in an excited state. When these dimers decay, they return to their ground state as a pair of argon atoms, and the energy difference between the excited dimer state and the ground state is released as a photon. There's a pretty good explanation here: https://microboone-exp.fnal.gov/public/talks/LArTPCWorkshopScintLight_bjpjone_2014.pdf — Preceding unsigned comment added by Waqarmuh (talk • contribs) 22:39, 4 July 2019 (UTC)
