Production and study of new neutron-rich nuclei via a novel MNT-induced process using 238U+164Dy — •Deepak Kumar¹, Paul Constantin², and Timo Dickel¹ for the FRS Ion Catcher collaboration — ¹GSI Helmholtz Center for Heavy Ion Research and Justus-Liebig University of Giessen, Germany — ²ELI-NP/IFIN-HH, Magurele, Romania

The crux of measuring the nuclear properties of heavy neutron-rich exotic nuclei and nuclear data with reduced uncertainties for known nuclei is to explore the r-process abundance pattern of the elements heavier than iron (Fe). However, the production of these neutron-rich nuclei is beyond the accessible limit of conventional methods. Nevertheless, a new possible alternative is the Multi-Nucleon Transfer (MNT) approach that manifests a strong potential to achieve this goal. In order to establish a new direction of research for the MNT-induced neutron-rich products using the FRS Ion Catcher (IC) facility at GSI, the 238U beam at 500 MeV/u has been proposed to deliver from the SIS18 and allowed to bombard on 164Dy target at 10 MeV/u placed inside the Cryogenic Stopping Cell (CSC). It offers a promising way to produce a significant amount of several new neutron-rich nuclei that have been speculated by the most reliable state-of-the-art Langevin-type model calculations. This research direction is based on a universal, fast, and efficient method to measure production cross-section and broadband masses of reaction products, including long-lived isomers. The developed methods and instrumentation will be extended to be utilized for LEB at the Super FRS facility with neutron-rich unstable beams.
