This generic mechanism in open quantum systems explains the phenomenological Ikeda diagram and generalizes it for various clusters/correlations in the vicinity of the respective cluster decay thresholds. The near-threshold collectivization of the SM states may also influence their electromagnetic decays. We discuss this phenomenon on the example of B(EL) decays of near-threshold 2+ states in 14C.", "revisions": [ { "version": "v1", "updated": "2019-10-15T05:06:53.000Z" } ], "analyses": { "keywords": [ "electromagnetic transitions", "near-threshold resonances", "open quantum systems explains", "collectivity", "common decay channel" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
