Abstract

A search for new isotopes using in-flight fission of a 345 MeV/nucleon ²³⁸U 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: ⁷¹Mn, ^73,74Fe, ⁷⁶Co, ⁷⁹Ni, ^81,82Cu, ^84;85Zn, ⁸⁷Ga,⁹⁰Ge, ⁹⁵Se,⁹⁸Br, ¹⁰¹Kr, ¹⁰³Rb, ^106,107Sr, ^108,109Y, ^111,112Zr, ^114,115Nb, ^115,116,117Mo, ^119,120Tc, ^{121,122,123,124}Ru, ^{123,124,125,126}Rh, ^127,128Pd, 133Cd, ¹³⁸Sn, ¹⁴⁰Sb, ¹⁴³Te, ¹⁴⁵I, ¹⁴⁸Xe, and ¹⁵²Ba.
