In bombardments of {sup 238}U targets with 186-MeV {sup 34}S projectiles we discovered the {alpha}-decaying nuclide {sup 267}108 with a half-life of 19{sub {minus}10}{sup +29} ms, {ital E}{sub {alpha}}=9.74 to 9.87 MeV, and a production cross section of about 2.5 pb. The new nuclide was identified by measuring correlations in energy, time, and position to establish genetic links between its implantation in a position-sensitive silicon detector and subsequent {alpha} decay followed by {alpha} decays of known descendant nuclides.
