…He was interned during World War I, but returned to England after the war and from 1919 he again worked with Rutherford at the Cavendish Laboratory. He was mainly involved in research into the nuclear transformation of light elements using natural alpha particles, but in 1930, inspired by the discovery by Walter Bothe (1891-1957) and Herbert Becker of Germany that a more penetrating radiation than gamma rays was produced during nuclear reactions, he began to investigate this new radiation. Through experiments using detection devices such as counters, cloud chambers, and high-voltage electrolysis chambers, he confirmed in 1932 that the new radiation was composed of electrically neutral particles with approximately the same mass as a proton. … *Some of the terminology that mentions "Bothe, W." is listed below.

…第1次世界大戦中は抑留されたが,終戦後イギリスに戻り,19年からキャベンディシュ研究所で再びラザフォードとともに研究に従事した。主として天然のα粒子による軽元素の原子核変換の研究に携わっていたが,30年ドイツのボーテWalter Bothe(1891‐1957)とベッカーHerbert Beckerが核反応に際してγ線より透過力のある放射線が出ることを発見したのに触発されて,この新放射線の究明に乗り出した。計数管,霧箱,高圧電離箱などの検出装置を用いる実験によって,32年その新放射線が陽子とほぼ同じ質量をもつ電気的に中性の粒子からなることを確証した。… ※「Bothe,W.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
