24 янв 1932 г. - Discovery of Neutrons:
Neutrons were discovered in
1932 by James Chadwick. Before
the experiment a 3rd particle
had been proposed to account
for missing mass. They knew
that it would weigh the
same as a proton and have
no charge. The existence of
the particle was confirmed by
James and he won the 1935
Nobel physics prize.
