Adjective
neutron-rich (comparative neutron-richer or more neutron-rich, superlative neutron-richest or most neutron-rich)
(nuclear physics, of a nucleus or isotope) Having a large ratio of neutrons to protons
Antineutrinos are made in the beta-decay of neutron-rich daughter fragments in the fission process. Source: Internet
At the first level of control in all nuclear reactors, a process of delayed neutron emission by a number of neutron-rich fission isotopes is an important physical process. Source: Internet
There had been evidence of dineutron emission from neutron-rich isotopes such as beryllium -16 where mononeutron decay would result in a less stable isotope. Source: Internet
The r-process is responsible for our natural cohort of radioactive elements, such as uranium and thorium, as well as the most neutron-rich isotopes of each heavy element. Source: Internet
