In bombardments of 238U targets with 186-MeV 34S projectiles we discovered the α-decaying nuclide 267108 with a half-life of 19-10+29 ms, Eα = 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 α decay followed by α decays of known descendant nuclides.
