Revision of Analytical Properties of Reaction Amplitude near Thresholds Using the Example of Muon-Induced Prompt Fission

TL;DR

This paper analyzes muon-induced prompt fission data near thresholds, comparing experimental results with theory, highlighting good agreement in some transitions and a surprising anomaly in nonradiative widths, and discusses potential resolutions.

Contribution

It provides a detailed comparison of experimental data with theoretical predictions for muon-induced prompt fission near thresholds, identifying specific anomalies and discussing possible explanations.

Findings

Good agreement for 2p to 1s and 3d to 1s transitions

Anomalously large nonradiative width for 3d to 1s transition

Discussion of potential solutions to the observed puzzle

Abstract

Experimental data on the muon-induced prompt fission are analyzed and compared to theory. Good agreement is observed for the 2p to 1s and 3d to 1s transitions. Anomalously big nonradiative width in the case of 3d to 1s transition is surprised. Ways of resolving this puzzle are discussed.
