The Rapid Communications section is intended for the accelerated publication ofimportant new results. Since manuscripts submitted to this section are given priority treatment both in the editorial office and in productiona, uthors should explain in their sub mittal letter why the work justt'ftes this special handling A. Rapid Communication in Physical Review D should be no longer than jtve printed pages and must be accompanied by an abstract.
