Preferred Label : tunnelling;
IUPAC definition : The process by which a particle or a set of particles crosses a barrier on its potential-energy
(reaction) surface without having the energy required to surmount this barrier. Since
the rate of tunnelling decreases with increasing reduced mass, it is significant in
the context of isotope effects of hydrogen isotopes.;
