Two hydrogen nuclei and a hole bind to the triple acceptor copper in germanium. The result is a single acceptor whose electronic states are modified by a coupling to the zero-point motion of the nuclei. That motion displays a qualitative change from rotation to libration induced by an increase in hydrogen isotopic mass. The acceptor A(CuH/sub 2/) has full tetrahedral symmetry and a complex ground-state manifold. All heavier isotope combinations display only a single ground-state component of symmetry lower than tetrahedral.
