THE view has recently been put forward1 that a neutral particle of about electronic mass, and spin ½h (where h = h/2π) exists, and that this ‘neutrino’ is emitted together with an electron in… Expand

ALTHOUGH it seems very unlikely that neutrinos, after having been emitted in a nuclear process, give rise to any detectable ionisation1, we would like to point out that it is not impossible in… Expand

The new information regarding the absorption of high energy photons and electrons, presented at the recent International Congress on Nuclear Physics, suggests an improved interpretation of certain… Expand

THIS book gives a very complete account of the quantum theory of collisions. In an introductory chapter, some theorems of wave mechanics are stated. The following four chapters are devoted to such… Expand

UNTIL recently, the theory of conductivity put forward by Sommerfeld and Bloch did not succeed in explaining the change of resistance in magnetic fields. If R' is the resistance in a magnetic field… Expand
