Near-100% Production Of The Excited Be+ 1S22P Ion From Decay Of Be 1S2S22P

Abstract

In examining the decay of photon-produced Be 1s2s2np(1P), n=2,3, we discovered that the vastly predominant decay mode is to the final excited ionic states Be+ 1s2np, rather than the ground state. For n=2, the 2p ion accounts for 95% of the total production, with Be+ 1s23p the other main contributor. For n=3, 3p is predominant, again with a very small fraction of 2s. The result for n=2 occurs as a consequence of the similarity between the 2s and 2p radial wave functions of the excited state, which leads to a cancellation in the amplitude for transition to the 2s ground state. © 1990 The American Physical Society.
