Abstract

A search for new isotopes in the neutron-rich rare-earth region has been carried out using a 345 MeV/nucleon ²³⁸U beam at the RIKEN Nishina Center RI Beam Factory. Fragments produced were analyzed and identified using the BigRIPS in-flight separator. We observed a total of 29 new neutron-rich isotopes: ¹⁵³Ba, ^154,155,156La, ^156,157,158Ce, ^{156,157,158,159,160,161}Pr, ^162,163Nd, ^164,165Pm, ^166,167Sm, ¹⁶⁹Eu, ¹⁷¹Gd, ^173,174Tb, ^175,176Dy, ^177,178Ho, and ^179,180Er.
