Nuclear Decay

  1. Jun 4, 2012 #1
    Hello,

    Would all radioactive decay lead to a daughter nuclide in a "nuclear excited" state, and if so, would this indicate that gamma rays are emitted in order for the nuclear ground/stable state to be reached after any decay?

    Also, if nuclear decay occurs b/c of the imbalance of the nucleus's attractive strong nuclear force and the repulsive electrostatic force, why is it said that a "weak force" is the cause for decay? Thanks a lot.

    No. But it is quite frequent.

    The transition neutron<->proton is done via the weak interaction (or "weak force"). Strong and electromagnetic interaction cannot transform these particles.
