NoteTable 7 in this preprint was corrected shortly after it was first produced. The corrected version, carrying the same front page as the original version, was widely circulated early in the spring of 1964. However, the corrected version was never captured by the CERN Archive. Attached to this record, as "additional file", is the version kept in the CERN Archive. In addition there is a document, with the same title, referred to as "Version 1". This document corresponds toCERN preprint 8182/TH.401, Jan. 17, 1964. |
