    Graduate Comparing D0 Decay Rates: K(-) + (pi)(+) vs. K(-) + e(+) + (v_e)

    Which of the following should occur at a greater rate: D0 to K(-) + (pi)(+) OR D0 to K(-) + positron + electron-flavor neutrino? I know that there are other decays that are Cabibbo supressed (or doubly so) but I can't see what would make one of these more likely than the other. Thanks

    Graduate Rho(0) Meson Decay: Forces & Strengths

    Can the rho(0) meson decay to a pion(0)+gamma ray? If so, which, between this decay and the decay to pion(+) + pion(-) dominates? I know decay modes will dominate as a result of the relative strength of fundamental forces involved, so what are the forces and their relative strengths in this...

    Graduate Why do some unexpected isotopes occur naturally?

    Thanks - is this because there is a difference in the orbital angular momentum of the parent and daughter nuclei? I know it HAS a really long half-life, but I don't know how to prove that to myself - what are it's features that result in this?

    Graduate Why do some unexpected isotopes occur naturally?

    Why do some isotopes occur naturally even though a seemingly valid decay with non-negligible energy release ~Mev, could energetically happen? E.g. Cadmium-106 could decay to Palladium-106 but it is still NATURALLY occurring?
