  Polarized atomic beam sources have been in operation since many years to
produce either nuclear polarized atomic hydrogen or deuterium beams. In recent
experiments such a source was used to polarize both isotopes independently at
the same time. By recombination of the atoms, HD molecules with all possible
nuclear spin combinations can be created. Those spin isomers are useful for
further applications like precision spectroscopy, as polarized targets for
laser-particle acceleration, polarized fuel for fusion reactors or as an option
for future measurements of electric dipole moments.
