Excitation functions were measured for the 52Cr(n,2n)51Cr, 52Cr(n,p)52V, 53Cr(n,p)53V, 53Cr(n,np+pn+d)52V, 54Cr(n,p)54V, 54Cr(n,np+pn+d)53V and 54Cr(n,a)51Ti reactions from 9 MeV to 21 MeV. Use was made of the activation technique in combination with high-resolution gamma -ray spectrometry. Monoenergetic neutrons produced via the 2H(d,n)3He and 3H(d,n)4He reactions were used to irradiate samples of metallic chromium, 52Cr203, 53Cr203 and 54Cr203. The neutron fluence rates were determined via the 27Al(n,p)27Mg, 27Al(n,a)24Na, 56Fe(n,p)56Mn and 93Nb(n,2n)92mNb monitor reactions. Short-lived activities were investigated using a pneumatic sample transport system. Statistical model calculations taking into account preequilibrium effects were performed for all reactions using a consistent set of model parameters. The experimental excitation functions helped appreciably to resolve the discrepancies in evaluated date files. Good agreement was found between the experimental data and the new model calculations.
