6li 28si reaction cross sections at sub barrier energies

Total reaction cross sections at near barrier energies (9-13 MeV) were measured for the system 6Li+28Si adopting a new technique. The results will be discussed in terms of the threshold anomaly at barrie

Measurement of the 241Am(n, 2n) Reaction Cross Section, by the Activation Method

In the context of the n TOF collaboration, the measurement of the cross section of the reaction 241Am(n, 2n)240 Am, has been performed, for the first time at neutron energies from 8.8, to 11.4MeV, by the activation method, relative to the 27Al(n, a)24Na reaction reference cross section. The monoenergetic neutron beam was produced at the 5.5MV TANDEM accelerator of NCSR “Demokritos”, by means of the 2H (d, n)3 He reaction, using a deuterium filled gas cell. The radioactive target consisted of a 37GBq 241Am source enclosed in a Pb container. After the end of the irradiation, the activity induced by the neutron beam at the target and reference, was measured off-line by a 56 % relative efficiency, HPGe detector.JRC.D.5-Neutron physic
