Abstract

The search for new isotopes using the in-flight fission of a ²³⁸U beam has been conducted concurrently with decay measurements, during the so-called EURICA campaigns, at the RIKEN Nishina Center RI Beam Factory. Fission fragments were analyzed and identified in flight using the BigRIPS separator. We have identified the following 36 new neutron-rich isotopes: ¹⁰⁴Rb, ¹¹³Zr, ¹¹⁶Nb, ^118,119Mo, ^121,122Tc, ¹²⁵Ru, ^127,128Rh, ^129,130,131Pd, ¹³²Ag, ¹³⁴Cd, ^136,137In, ^139,140Sn, ^141,142Sb, ^144,145Te, ^146,147I, ^149,150Xe, ^149,150,151Cs, ^153,154Ba, and ^{154,155,156,157}La.
