The monoenergetic neutron beam was produced at the 5.5 MV TANDEM accelerator of NCSR ""Demokritos, "" by means of the H2(d,n)He3 reaction, using a deuterium filled gas cell. The radioactive target consisted of a 37 GBq Am241 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. © 2006 The American Physical Society.http://hdl.handle.net/123456789/17358ISI:00023869750004710.1103/PhysRevC.73.06760160556-281373engAMERICAN PHYSICAL SOCPhysical Review C - Nuclear PhysicsENERGYTHRESHOLDNEUTRON SOURCEWASTE TRANSMUTATIONActive MethodsCross SectionMeasurement of the Am241(n,2n) reaction cross section using the activation methodjournalArticle2006Δημοσίευση σε περιοδικόPublication in journalΠυρηνική φυσικήNuclear Physicsisi - Physics, Nuclear includes resources on the study of nuclear structure, decay, radioactivity, reactions, and scattering.
