Purpose: We investigate the impact of the particle continuum on proton and neutron ANCs for mirror systems from $p$- and $sd$-shell regions. Method: We use the real-energy and complex-energy continuum shell model approaches. Results: We studied the general structure of the single-particle ANCs as a function of the binding energy and orbital angular momentum. We computed ANCs in mirror nuclei for different physical situations, including capture reactions to weakly-bound and unbound states. Conclusions: We demonstrated that the single-particle ANCs exhibit generic behavior that is different for charged and neutral particles. We verified the previously proposed relation [N.K.

C 72, 064324 (2005)] between proton and neutron mirror ANCs. We find minor modifications if the spectroscopic strength is either localized in a single state or broadly distributed. For cases when several states couple strongly to the decay channel, these modifications may reach 30%.", "revisions": [ { "version": "v1", "updated": "2012-03-17T20:13:19.000Z" } ], "analyses": { "subjects": [ "21.10.Jx", "21.60.Cs", "21.10.Sf", "24.10.Cn" ], "keywords": [ "asymptotic normalization coefficient", "mirror nuclei", "continuum coupling", "complex-energy continuum shell model approaches", "single-particle ancs" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevC.85.064320", "journal": "Physical Review C", "year": 2012, "month": "Jun", "volume": 85, "number": 6, "pages": "064320" }, "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1094211, "adsabs": "2012PhRvC..85f4320O" } } }
