Gamma-ray transition between 9− and 8− levels in178Hf measured in178Ta 2.45 h decay

Гамма-переход между уровнями 9− и 8− в178Hf, измеренный при распаде178Ta с временем жизни 2.45 часа

Il Nuovo Cimento A (1965-1970)

Summary

A gamma-ray transition in the decay of the178Ta 2.45 h isomer with an energy of (216.7±0.1) keV and half-life (3±1) h was detected. This transition was interpreted as taking place between the 9− and 8− levels of178Hf. Intraband transition intensity rules and possible Nilsson configurations determine the value 7− for the spin and parity of178Ta 2.45 h.

Riassunto

Si è determinata una transizione dei raggi gamma nel decadimento dell'isomero178Ta 2.45 h con un'energia di (216.7±0.1) keV e una vita media di (3±1) h. Questa transizione è stata interpretata aver luogo tra i livelli 9− e 8− del178Hf. Le regole di intensità di transizione tra bande e le possibili configurazioni di Nilsson determinano il valore 7− per lo spin e la parità del178Ta 2.45 h.

Резюме

Наблюдается гамма-переход при распаде изомера178Ta 2.45 часа с энергией (216.7±0.1) кэВ и временем жизни (3±1) часа. Этот переход интерпретируется как переход между уровнями 9− и 8− в178Hf. Правила интенсивностей междузонных переходов и возможные конфигурации Нильсона определяют значение 7− для спина и четности178Ta 2.45 часа.
