Fate of muon in atom

  1. Sep 27, 2012 #1
    I find that I cannot find some simple and basic data - when I search, I find recent articles working on advanced extra experiments, but basic facts are taken for granted there and not repeated.

    What happens to a muon in an atom?

    Obviously, a free muon decays
    μ->e+ν~e+νμ
    with lifetime about 2,2*10^-6 s
    A muon in atom might do the same.
    But the muon in atom has an alternative reaction available:
    p+μ->n+νμ
    What is the branching ratio, in the ground state of mu hydrogen, between mu decay and muon capture?

    Try this rather long survey on Nuclear Muon Capture.
