Abstract :
We present fission cross-section measurements with ∼ 10 ng of 239Pu performed using the LANSCE Lead Slowing-Down Spectrometer. Results of Li 6 ( n , α ) measurements with a sample size of 760 ng of 6Li are also reported. This technical achievement demonstrates the feasibility of measuring neutron-induced fission cross-section on samples with 10 ng of fissile actinides that are available on ultra-small quantities. Furthermore, results on neutron-induced alpha emission show that measurements for astrophysics purposes are feasible with the LSDS.
