Extractions: 10.1103/PhysRevD.34.722 Bibliographic Code: Abstract The magnetic moment of a free electron has been measured by observing both its low-energy spin and cyclotron resonances (at nu s =omega s /2pi and nu c =omega c /2pi, respectively) by means of a sensitive frequency-shift technique. Using radiation and tuned-circuit damping of a single electron, isolated in a special anharmonicity-compensated Penning trap, also cooled to 4 K, the electron's motion is brought nearly to rest, thus preparing it in a cold quasipermanent state of the geonium ``atom.'' The magnetic-coupling scheme, described as a continuous Stern-Gerlach effect, is made possible through a weak Lawrence magnetic bottle which causes the very narrow axial resonance, at nu

Fisici fisico statunitense di origine tedesca (Görlitz 1922). Studiò a Breslavia e, finita la guerra, si laureò a Gottinga. Trasferitosi negli Stati Uniti, ne assunse la cittadinanza nel 1961. Nello stesso anno iniziò a insegnare all'Università di Washington. È membro dell'Accademia nazionale delle Scienze degli Stati Uniti. È riuscito, perfezionando la trappola di Penning (che utilizza un forte campo magnetico statico e un debole campo elettrico statico) a isolare per l'osservazione un singolo elettrone (1973), e a studiarne quindi meglio le proprietà . Ha ideato un metodo – basato sull'impiego di un laser – per raffreddare elettroni e ioni , cioè fino a ridurne l'energia quasi al limite teorico; è stato così possibile misurare le frequenze atomiche e i singoli salti quantici con una precisione prima irraggiungibile. Nel 1989 gli è stato conferito, con

Extractions: Né à Görlitz (Allemagne), Dehmelt obtient son doctorat en 1950 à l'université de Göttingen. Il travaille plusieurs années comme chercheur à l'institut Hans Kopfermann de Göttingen. En 1952, il part aux États-Unis et mène des recherches à l'université Duke. En 1955, il entre à la faculté de l'université de Washington où il poursuit ses recherches et continue à enseigner. À partir des travaux de Wolfgang Pauli , Dehmelt tente, à l'aide d'un champ électrique tridimensionnel (le piège de Paul), de confiner des ions en suspension dans un espace réduit. En 1973, en appliquant à ce dispositif un champ magnétique puissant, il parvient à isoler et à conserver un seul électron. Il utilise ce système, appelé piège de Penning, pour étudier les propriétés magnétiques et les états de spin des électrons. Dehmelt met aussi au point une technique permettant de refroidir les particules étudiées de manière à ralentir leur mouvement et donc à accroître la précision des mesures faites. Dehmelt perfectionne ensuite ses techniques d'étude de particules atomiques et augmente la précision des mesures magnétiques relatives aux électrons. En 1980, il parvient à isoler, à refroidir et à photographier un seul ion dans le piège de Penning. En 1989, il a reçu le prix Nobel de physique avec le physicien allemand
