In a nuclear decay, where the dM energy goes?

[ORF]

Hello

Let's suppose a beta-decay. The mother nucleus is dM heavier than the daughter nucleus.

What happen if the excitation energy does not match any combination of excited states in the daughter nucleus?

Example: the daughter nucleus has 100keV of excitation energy, but the first exited state is at 200keV. Will the energy be kept in the nucleus until an internal conversion?

Thank you in advance.

Greetings

The excess energy in a beta decay is generally distributed among the decay products. Since the nuclei are heavy, most of the energy goes into kinetic energy in the resulting electron/positron and (anti)neutrino.
