Norman Feather FRS [1] FRSE PRSE (16 November 1904 – 14 August 1978), [4] was an English nuclear physicist. Feather and Egon Bretscher were working at the Cavendish Laboratory , Cambridge in 1940, when they proposed that the 239 isotope of element 94 ( plutonium ) would be better able to sustain a nuclear chain reaction .
Almost coincident with their discovery, neutrons were used by Norman Feather, Chadwick's colleague and protege, in scattering experiments with nitrogen. [91] Feather was able to show that neutrons interacting with nitrogen nuclei scattered to protons or induced nitrogen to disintegrate to form boron with the emission of an alpha particle ...
Quebec Agreement. The Quebec Agreement was a secret agreement between the United Kingdom and the United States outlining the terms for the coordinated development of the science and engineering related to nuclear energy and specifically nuclear weapons. It was signed by Winston Churchill and Franklin D. Roosevelt on 19 August 1943, during World ...
Typically, a neutron on its own would be bouncing around too fast to be trapped and measured. To solve that problem, neutrons are cooled down, which makes the particle slow down to about 18 mph ...

President Franklin D Roosevelt and British Prime Minister Winston Churchill during the Quebec Conference, 18 August 1943, at which the mechanism for cooperation on Tube Alloys was agreed upon.

At the Cavendish Laboratory in Cambridge, Egon Bretscher and Norman Feather realized that a slow neutron reactor fuelled with uranium would theoretically produce substantial amounts of plutonium-239 as a by-product. They calculated that element 94 would be fissile, and had the added advantage of being chemically different from uranium, and ...
The breakthrough with plutonium was by Bretscher and Norman Feather at the Cavendish Laboratory. They realised that a slow neutron reactor fuelled with uranium would theoretically produce substantial amounts of plutonium-239 as a by-product.
He was Rutherford's assistant director of research at the Cavendish Laboratory for over a decade at a time when it was one of the world's foremost centres for the study of physics, attracting students like John Cockcroft, Norman Feather, and Mark Oliphant. Chadwick followed his discovery of the neutron by measuring its mass. He anticipated that ...
