Abstract
Multi-nucleon transfer (MNT) reactions are experiencing renewed interest as a mechanism for producing heavy elements. At facilities like IGISOL [1] and NEXT [2], transfer products are collected in gas cells before precision measurements. While this method covers a large solid angle, it does not allow the study of the fast decay of reaction products or in-beam spectroscopy at the collision area.
Complementing these efforts, RITU [3] at Jyväskylä Accelerator Laboratory (JYFL), enables the study of a fraction of transfer products emitted at zero degrees from the beam. By combining the gas-filled separator RITU with the JUROGAM [4] detector array, transfer products can be identified through their prompt γ-ray emissions at the target position, coinciding with recoil detection at RITU’s focal plane. This setup provides direct insights into the reaction mechanisms, facilitating the study of kinematics and the determination of differential cross sections.
Experiments using the 64-Ni + 238-U reaction were conducted at energies close to the Coulomb barrier to find the optimal energy for maximal production of heavy transfer products. In this energy regime, many transfer products are expected to be emitted in the forward direction at small angles. The poster will provide an overview of the experiment, present the current status of the data analysis, and propose strategies for identifying MNT products.
