Summary
The176Lu decay scheme was investigated by means of the175Lu(nth, γ) reaction. The (2÷6) MeV γ-ray spectrum was measured with a Ge(Li) spectrometer and a decay scheme was constructed by means of the Ritz combination method. Some rotational bands not previously observed were identified. The intrinsic configuration of each one is discussed on the basis of the known levels of neighbouring nuclei.
Riassunto
Lo schema di decadimento del176Lu è stato studiato mediante la reazione175Lu(nth, γ)176Lu. Lo spettro gamma nell’intervallo (2÷6) MeV è stato misurato con uno spettrometro al Ge(Li). Mediante il metodo di Ritz è stato costruito uno schema di decadimento. Si sono trovate alcune bande rotazionali non precedentemente osservate. Ad ognuna è stata attribuita una configurazione sulla base dei dati sui nuclei vicini.
Реэюме
С помошью реакции175Lu(nth, γ) исследовалась схема распада178Щи. Спектр гамма-лучей в области (2 ÷ 6) МзВ иэмерялся с помошью детектора Ge(Li) и посредством комбинационного метода Ритца конструировалась схема распада. Идентифицировались некоторые ротационные эоны, которые ранее не наблюдались. На основе иэвестных уровней соседних ядер обсуждается внутренняя конфигурация каждой эоны.
