To the Theory of Unstable States

TL;DR

This paper argues that deviations from exponential decay laws are theoretically predicted only when advanced interactions are ignored, and confirms that exponential decay is valid within quantum field theory considering interaction durations.

Contribution

It demonstrates that non-exponential decay contributions arise from neglecting advanced interactions, reaffirming exponential decay as fundamental in quantum field theory.

Findings

Deviations from exponential decay are due to ignoring advanced interactions.

Exponential decay is supported within quantum field theory when considering interaction durations.

Experimental proof of non-exponential decay remains absent.

Abstract

Deviations of the decay law from exponents are discussing for a long time, however, experimental proofs of such deviations are absent. Here in the general form is shown that the conclusions about non-exponential contributions are due to the disregarding of advanced interactions, i.e. at principally non-relativistic considerations. We consider decay processes in the frame of interactions duration of the quantum field theory. We show that at this basis the usual exponential decay has place.
