Electron capture in fully ionised nuclei

    Hello everyone,
    What happens if an isotope that normally decays through EC has no electrons at all? For example how does 7Be4+ decay?

    If beta+ decay is not possible and there are no electrons around, the isotope becomes stable.

    Positron emission is energetically blocked for Be-7, so it becomes stable.

    Most heavier nuclei will have the positron emission channel open up.
