Low-lying excited states in nuclei

[kelly0303]

Hello! How are the parity and spin of excited states of nuclei measured experimentally. I imagine that the energy can be easily measured by exciting the nucleus (by colliding it with a nucleon or electron for example) and then measuring the emitted photons. But how can one infer the spin and parity associated with that decay? Thank you!

Measure which transitions are allowed, and if possible measure the angular spectrum of emitted photons.

Hi,

you can also compare with theoretical shell model calculations, and assign spin and parities from these models.
