The {sup 96}Mo(d,{sup 2}He){sup 96}Nb charge-exchange reaction was investigated at an incident energy of E{sub d}=183.5 MeV. An excitation-energy resolution of 110 keV was achieved. The experiment was performed at KVI, Groningen, using the magnetic spectrometer BBS at three angular positions: 0 deg., 2.5 deg., and 6 deg. We found that below 6 MeV almost the entire Gamow-Teller (GT{sup +}) strength is concentrated in a single state at 0.69 MeV excitation energy. As {sup 96}Mo is the daughter of the {beta}{beta} decay nucleus {sup 96}Zr, the present result provides information about the nuclear matrix elements active in the 2{nu}{beta}{beta} decay of {sup 96}Zr.
