Abstract

The magnetic moment of the Σ+hyperon has been measured to be 35±12 nuclear magnetons by observing the precession of the polarization vector in a pulsed magnetic field The polarized hyperons were produced in a liquidhydrogen target by a beam of 117 Ge V/c π+meson and their decay was detected in pellicles of nuclear emulsion The final direction of the polarization was determined from the angular distribution of the decay Σ+→pπ0Было измерено что магнитный момент Σ+hyperon гиперона равен 35±12 ядерных магнетонов путем наблюдения прецессии вектора поляризации в пульсирующем магнитним поле Поляризованные гипероны рождаются в жидкостноводородной мишени посредством пучка π+meson мезонов с импульсом 117 ГэВ/с и их распад определяется в пленках ядерной эмульсии Окончательное направление поляризации определяется из углового распределения распада Σ+→pπ0Si riporta una misura del momento magnetico dell’iperone Σ+hyperon effettuata osservando la precessione del vettore polarizzazione in un campo magnetico impulsato Il valore trovato è 35±12 magnetoni nucleari Gli iperoni polarizzati sono stati prodotti inviando un fascio di mesoni π+meson di 117 GeV/c in idrogeno liquido ed il loro decadimento è stato rivelato in emulsione nucleare La direzione finale del vettore polarizzazione è stata determinata per mezzo della distribuzione angolare del decadimento Σ+→pπ0
