Abstract
A beam of ammonia molecules including the isotopes N.sup.15 H.sub.3 and N.sup.14 H.sub.3 is generated wherein some of the molecules of each isotope reside in an asymmetric energy state and other of the molecules of each isotope reside in a symmetric energy state. The symmetric state molecules are removed from the beam in a first state selector to provide a beam containing substantially only asymmetric state molecules of each isotope. The latter beam is fed to a resonant microwave cavity where it interacts with microwaves of a frequency inducing asymmetric state to symmetric state transitions for molecules of one of the isotopes but not for molecules of the other isotope. Either the asymmetric state molecules or the symmetric state molecules are removed from the resultant beam in a second state selector to provide a beam containing substantially only molecules of the other energy state enriched in the isotope N.sup.15 H.sub.3.
