…the first experiment to prove that the angular momentum vector of a charged particle moving through a magnetic field can only take directions such that the component along the magnetic field is one of several specific discrete values (directional quantization). In 1921, O. Stern and Walter Gerlach (1889-1979) of Germany squeezed silver atoms ejected from a heated furnace into a thin beam through a slit and passed it through a magnetic field whose strength increased rapidly from bottom to top. The beam was clearly split into two directions, up and down. … *Some of the terminology that mentions "Gerlach, W." is listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…磁場の中を運動する荷電粒子について,その角運動量ベクトルは磁場方向の成分が特定のとびとびの値のどれかになるような方向しかとらないこと(方向量子化)を証明した最初の実験。1921年,ドイツのO.シュテルンとゲルラハWalter Gerlach(1889‐1979)は加熱した炉から噴出する銀原子をスリットで絞って細いビームとし,下から上に向かい急激に強さを増す磁場を通したところ,ビームは上下の2方向に截然と分裂した。… ※「Gerlach,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 |
