The reason is very simple: the position of the \"iron knee\" depends on an answer to the questions: \"What do we see at 3-5 PeV? Is the knee seen at this energy associated with proton or iron primaries?\"", "revisions": [ { "version": "v1", "updated": "2010-11-21T20:23:52.000Z" } ], "analyses": { "keywords": [ "cosmic ray spectrum", "iron knee", "iron primaries" ], "note": { "typesetting": "TeX", "pages": 3, "language": "en", "license": "arXiv", "status": "editable", "inspire": 878362, "adsabs": "2010arXiv1011.4695S" } } }
