Doubly charged negative hydrogen ions H$sup 2-$ and D$sup 2-$ have been indirectly observed in a tandem mass spectrometer using a hollow cathode duoplasmatron ion source. The half-life of these doubly charged ions, determined in a number of drift time experiments, is 23+-4 nsec. The existence of these ions is concluded from a velocity, momentum, and energy analysis of hydride ions produced in the autodetachment process: X$sup 2-$$Yields$$X$$sup -$+e (X=H,D). (AIP)
