Neutrino mass problem: the state of the art

Investigation of neutrino properties in experiments at nuclear reactors: Present status and prospects

“…Relations (7) and ( 8) demonstrate that, for example, at a distance of I km from the reactor, the sensitivity of the experiment being discussed is the highest at ∆m 2 ≈ 5 × 10 −3 eV 2 and that it becomes poorer fast as ∆m 2 decreases.…”

“…An extensive list of references on the problem of neutrino oscillations from the studies of Pontecorvo and his colleagues [5], an account of the theory and of the phenomenology of this phenomenon, and a description of the experiments that had been performed prior to 1997 can be found in the review articles [6,7].…”
