Feather was therefore the first to show that neutrons produce nuclear disintegrations.
2.
At Manchester, he began investigation of the evaporation theory of nuclear disintegration.
3.
He investigated nuclear disintegration and made his reputation with the design of heavy high-voltage apparatus.
4.
A "'spinthariscope "'is a device for observing individual nuclear disintegrations caused by the interaction of ionizing radiation with a phosphor ( see radioluminescence ) or scintillator.
5.
The "'Cockcroft Walton ( CW ) generator "', or "'multiplier "', is an electric circuit that generates a high Ernest Thomas Sinton Walton, who in 1932 used this circuit design to power their particle accelerator, performing the first artificial nuclear disintegration in history.
6.
It was realized that such devices could be used in the detection and counting of Alpha particles in the nuclear disintegration experiments then being undertaken by Rutherford, who encouraged him to devote his attention to the construction of a reliable valve amplifier and methods of registering and counting particles.
7.
After much hard work and diligent coaxing of the cantankerous machine, he was eventually able to make a pair of successful runs, resulting in his dissertation : " Absolute Cross-Section for the Nuclear Disintegration H2 + H2 > H3 + H1 and Its Dependence on Bombarding Energy [ 50 to 380 keV ] ".
8.
This is a different process than the more random nuclear disintegration that precedes light fragment emission in ternary fission, which may be a result of a nuclear reaction, but can also be a type of spontaneous radioactive decay in certain nuclides, demonstrating that input energy is not necessarily needed for fission, which remains a fundamentally different process mechanistically.
