Abstract

Gamma lines 1·05 MeV(4 × 10−6 quanta/decay) and 1·14 MeV (9 × 10−6 quanta/decay), giving evidence of the existence of a new level in Hf176 with an energy of 1·14 MeV, were found in the decay of Lu176m with a half-life of 3·7 hours, using the scintillation method. The component of the beta spectrum, exciting this level, has a maximum energy of 0·17 MeV and logft=8·3. The spin of this level proved to be equal to one. The level was interpreted as a single-particle neutron level withn 0: 5/2− (512),n 1: 7/2− (514);I=1+.

Abstract

При помощи сцинтиляционного метода были найдены при распаде Lu176m с периодом полураспада 3,7 часа γ-линии 1,05 MeV (4.10−6 квантов/распад) и 1,14 MeV (9.10−6 квантов/ /распад), свидетельствующие о новом уровне в Hf176 с энергией 1,14 MeV. Составляющая β-спектра, возбуждающая этот уровень, имеет максимальную энергию 0,17 MeV и logft = =8,3. Спин этого уровня был определен и равен единице. Уровень истолкован как одночастичный нейтронный уровень cn 0: 5/2− (512),n 1: 7/2− (514);I = 1+h
