The Nobel Prize in Physics 1995 was awarded jointly "for pioneering experimental contributions to lepton physics" to Martin L. Perl "for the discovery of the tau lepton" and Frederick Reines "for the detection of the neutrino."

In 1953 Reines and Cowan published "Detection of the Free Neutrino" (Physical Review 92, p830) where they noted "An experiment has been performed to detect the free neutrino. It appears probable that this aim has been accomplished although further confirmatory work is in progress." The further work took three years, when in 1956, Cowan, et al published "Detection of the Free Neutrino: A Confirmation" (Science 124) confirming the previous work. That same year, Reines and Cowan published "The Neutrino" (Nature 178, p 446) with a history of work done to date and some new experimental results.

While Ezhela notes the paper offered here provides "Confirmation of the detection of the anti v(sub e) [i.e. anti-neutrino]" and it clearly is related to their earlier work ("identical in principle with that performed at Hanford in 1953"), the paper offered here is focused on a refinement in results to further confirm the work done in 1953 and 1956. Reines and Cowan reported that in 1956 an approximate value for the absoprtion cross section essential to the theory of the reaction predicted. This experiment modified the equipment used in order to "obtain a better value of the cross section."
