Double beta-decay

Двойной бета-распад

Il Nuovo Cimento A (1965-1970)

Summary

In this paper we study the double-beta-decay process in order to test the existence of an electronic lepton number conservation law. We give general formulae for the transitions 0+ → 0+, 0+ → 2+, 0+ → 4+ for neutrinoless double beta-decay. The double beta-decay of48Ca is studied in detail. From the experimental data we conclude that |δ − 1| ≤3·10−6.

Riassunto

In quest’articolo si studia il processo del doppio decadimento beta in modo da provare l’esistenza di una legge di conservazione del numero leptonico elettronico. Si danno formule generali per le transizioni 0+ → 0+, 0+ → 2+, 0+ → 4+ per decadimenti doppi beta senza neutrini. Si studia in dettaglio il doppio decadimento beta del48Ca. Dai dati sperimentali si conclude che |δ − 1| ≤3·10−6.

Реэюме

В зтой статье мы исследуем процесс двойного бера-распада, с целью проверки сушествования эакона сохранения злектронного лептонного числа. Мы приводим обшую формулу для переходов 0+ → 0+, 0+ → 2+, 0+ → 4+ в случае двойного бета-распада беэ нейтрино. Подробно иэучается двойной бета-распад48Ca. Иэ зкспериментальных данных мы выводим, что |δ−1|⩽3·10−6.
