Summary
In this paper we discuss the influence of a nonexponential decay on the determination of compound nuclear-reaction times by means of the blocking effect. In particular, with reference to the reaction92Mo(p, p′)92Mo*(2+, 10.5 MeV), the applicability of a cut-off model is shown. The difference between the reaction times deduced from experiments for exponential and nonexponential decay is calculated.
Riassunto
In questo lavoro si studia l’effetto di un decadimento non esponenziale sulla determinazione di tempi di reazione nucleari di nucleo composto tramite l’effetto blocking. In particolare, con riferimento alla reazione92Mo(p, p′)92Mo*(2+, 1.5 MeV), si mostra l’applicabilità del modello a cut-off e si calcola la differenza fra i tempi di reazione determinati dagli esperimenti sulla base di decadimenti esponenziali e non esponenziali.

В зтой работе мы обсуждаем влияние незкспоненциалыгого распада на определение времен жиэни компаунд-ядер с помошью зффекта блокировки. В частности, покаэывается применимость модели обреэания на примере реакции 92Мо(р, р.)92Мо* (2+, 1.5 МзВ). Вычисляется раэличие между временами реакции, полученными иэ зкспериментов, для зкспоненциального и незкспоненциального распадов.
