Abstract:
Neutron-induced reactions remain at the forefront of experimental investigations for the understanding of stellar nucleosynthesis and chemical evolution of the Galaxy. We report on experiments performed with the Liquid-Lithium Target (LiLiT) and a ~3 kW proton beam from the Soreq Applied Research Accelerator Facility (SARAF), yielding high-intensity 30-keV quasi-Maxwellian neutrons. First experiments were dedicated to benchmark the experimental system by measuring the Maxwellian Averaged Cross Section (MACS) of 94Zr and 96Zr, important isotopes for understanding the s-process evolution. The high neutron intensity enables MACS measurements of low-abundance or radioactive targets. Using α-, β-, γ-spectrometry and atom-counting techniques (accelerator mass spectrometry, atom-trap trace analysis), we are extending our experimental studies. In this talk some of our recent experiments and preliminary results will be presented.
