Cross sections of deuteron induced reactions on natCr up to 50 MeV: Experiments and comparison with theoretical codes

Activation of Cr-containing components around high energy deuteron accelerator can pose radioprotection problems for maintenance personnel. In a stacked foil irradiation, followed by high resolution gamma spectroscopy the cross sections for production of 46,47,48Sc, 51Cr, 52,54Mn and 48V were measured up to 50 MeV resulting in first systematic assessment above 15 MeV. Reduced uncertainty is obtained by simultaneous remeasurement of the Al(d,x)24Na or Ti(d,x)48V monitor reactions over the whole energy range. A comparison with experimental literature values and results from updated theoretical codes (ALICE-D, EMPIRE-D and the TENDL2010 on-line library) is discussed.
