A search for new isotopes using in-flight fission of a 345 MeV/nucleon 238 U beam has been carried out at the RI Beam Factory at the RIKEN Nishina Center. Fission fragments were analyzed and identified by using the superconducting in-flight separator BigRIPS. We observed 45 new neutron-rich isotopes: 71 Mn, 73,74 Fe, 76 Co, 79 Ni, 81,82 Cu, 84,85 Zn, 87 Ga, 90 Ge, 95 Se, 98 Br, 101 Kr, 103 Rb, 106,107 Sr, 108,109 Y, 111,112 Zr, 114,115 Nb, 115,116,117 Mo, 119,120 Tc, 121,122,123,124 Ru, 123,124,125,126 Rh, 127,128 Pd, 133 Cd, 138 Sn, 140 Sb, 143 Te, 145 I, 148 Xe, and 152 Ba.
