Neutron-induced reactions play a key role in stellar nucleosynthesis and chemical evolution of the Galaxy. While cross sections of neutron capture reactions on stable nuclei are well studied at stellar energies, measurements are rare for radioactive species, acting often as branching points between decay and capture ,which have to be produced artificially. A sample containing ~10 ¹⁸ atoms ⁵³Mn (t_1/2= 3.7 × 10 ⁶ yr) was prepared using a stock solution previously extracted and purified from an activated accelerator beam dump in the course of the ERAWAST initiative at Paul Scherrer Institute, Switzerland (PSI). A first experimental measurement of the Maxwellian Averaged Cross-Section (MACS) of ⁵³Mn at stellar neutron energies was performed at the Soreq Applied Research Accelerator Facility - Liquid-Lithium Target (SARAF- LiLiT) laboratory, which is dedicated to the study of s-process neutron capture reactions. A kW-power proton beam, at 1.946 MeV in the present experiment, from SARAF Phase I yields high-intensity ~30 keV quasi-Maxwellian neutrons (3-5×10 ¹⁰ n/s) which allow us to irradiate radioactive targets of very low mass. The ⁵⁴Mn (312 d) neutron-capture products were independently counted via their β-delayed γ activity (835-keV γ transition) in three laboratories. The preliminary analysis of the measurements performed at Hebrew University will be presented and compared to those of the other laboratories. The extraction of a MACS at stellar s-process temperature from the experimental results is in progress.
