Neutron-rich radioactive isotope (RI) beams in the vicinity of 110Zr were produced using the in-flight fission of a 345-MeV/nucleon 238U beam at the RIKEN Radioactive Isotope Beam Factory. The RI beams were separated in flight by the large-acceptance two-stage fragment separator BigRIPS. Isotopes were clearly identified in a low-background particle-identification plot, which was obtained from the measurements of time of flight, magnetic rigidity, and energy loss using beam-line detectors placed in the BigRIPS separator and the ZeroDegree spectrometer. Nine new isotopes, 101Br, 102Kr, 105,106Rb, 108Sr, 110,111Y, 114Zr, and 117Nb, are reported for the first time, with their measured production cross sections compared with the extrapolations of lighter isotopes down to the femtobarn regime.
