how to separate the neutron for penetrating the nucleus in Madam Quiry experiment?

Question

When madam quiry was doing the expt. of finding the alfa, beta,gama rays to penetrating the neutrons on nucleus of radiative atoms. Then how to separate the neutrons from the atom?

Answer 1

It's Madam Curie, not quiry

Answer 2

uh you're thinking of Marie Curie and she wasn't doing that. She found polonium and radium but didn't investigate the particles involved in the decay that much.

neutrons are stripped of via bombardment. the nucleus literally splits and releases them

fyi i'd put this in physics if you want a real answer
