Abstract
It is shown that a Dirac particle of mass m and arbitrarily small momentum will tunnel without reflection through a potential barrier V = U-c(x) of fi nite range provided that the potential well V = -U-c(x) supports a bound st ate of energy E = -m. This is called a supercritical potential well.
