Source sentences:
text: decay (positron emission) of a nucleus is allowed energetically, so too is electron capture allowed.
text: However, in nuclei where β decay is forbidden but ββ decay is allowed, the process can be seen and a half-life measured.
text: When considering whether a specific nuclear transmutation, a reaction or a decay, is energetically allowed, one only needs to sum the masses of the initial nucleus/nuclei and subtract from that value the sum of the masses of the product particles.
