Abstract
<jats:p>Half-lifes (<jats:italic>T</jats:italic><jats:sub>1/2</jats:sub>) of exotic neutron-rich isotopes of Ba, La, Ce, Pr, and Nd were measured at the RIKEN Nishina Center. The experimental setup consisted of the BigRIPS in-flight separator for ion selection identification, the Advance Implantation Detector Array (AIDA) for ions and β detection, and the BRIKEN detector for neutron counting. Using this setup, 4 new <jats:italic>T</jats:italic><jats:sub>1/2</jats:sub> have been measured for the first time, and 38 <jats:italic>T</jats:italic><jats:sub>1/2</jats:sub> have been remeasured with improved precision in several cases. These new experimental data should help to constrain theoretical models for calculations of <jats:italic>T</jats:italic><jats:sub>1/2</jats:sub>. The status of the experimental analysis and preliminary results are provided in this contribution.</jats:p>
