This is not true, I'm pretty sure. If you wing a neutron into a nucleus you may trigger a decay for example.
What you mean to say is that under the conditions under consideration (to be described) the decay happens "from the inside".
It would depend on the isotope in which the neutron hit.
ie:
Argon 39 + neutron Argon40 stable
potassium 39 + neutron Potassium 40 emits alpha eventually
Uranium238 + neutron Uranium239 emits beta becoming Neptunium239, emits beta becomes Plutonium239 emits alpha eventually
Uranium235 + slow neutron fissions into 2 nuclei of 2 elements between zinc & gadolinium further decays would depend on the isotopes created.
