BetaplusZerfall

BetaplusZerfall is a term found in theoretical discussions of nuclear decay that denotes a proposed decay channel combining beta-plus decay with an immediate, correlated transition of the daughter nucleus. In this conception, a nucleus would undergo beta-plus emission (positron emission) and, in close temporal proximity, experience a secondary electromagnetic transition that accompanies or is synchronized with the emitted positron. The idea is to describe a coupled process rather than a simple sequence of independent steps, though in practice the observable outcome can resemble a standard beta-plus decay followed by gamma emission.

The name BetaplusZerfall blends the German components Betaplus, referring to beta-plus decay, and Zerfall, meaning decay. In German-language nuclear physics literature, the term has been used to discuss hypothetical or model-dependent coupling effects between weak decay and electromagnetic transitions. The concept is primarily theoretical and serves to explore how simultaneous or tightly linked decay processes might alter energy spectra or branching patterns in certain isotopes.

In terms of status, BetaplusZerfall is not established as an experimentally confirmed, distinct decay channel. Standard beta-plus decay, often followed by gamma emission from excited states of the daughter nucleus, already accounts for many observed signatures. BetaplusZerfall remains a speculative construct that could, if realized, modify predicted energy distributions, angular correlations, or decay schemes in particular nuclear systems. Its relevance is mainly within frontier nuclear structure studies and the modeling of complex decay paths.

Related concepts include beta-plus decay, electron capture, gamma decay, and beta-delayed gamma emission. The term is most at home in theoretical discussions rather than as an established, separate category in nuclear data compilations.
