Özet

Excitation functions were measured for the Sc-45(n,2n)Sc-44(m), Sc-45(n,2n)Sc-44(m+g), and Mn-55(n,2n)Mn-54 reactions from threshold to 13 MeV, and for the Sc-45(n,p)Ca-45, Sc-45(n,alpha)K-42, Mn-55(n,p)Cr-55, and Mn-55(n,alpha)V-52 reactions over the neutron energy range of 6 to 13 MeV. The quasimonoenergetic neutrons were produced via the H-2(d,n)He-3 reaction using a deuterium gas target at a variable energy compact cyclotron. The activation technique in combination with high resolution gamma-ray spectroscopy was used. In the case of the Sc-45(n,p)Ca-45 and Mn-55(n,p)Cr-55 reaction products, ''low-level'' beta(-) counting was applied. The reaction product Ca-45 was separated radiochemically prior to beta(-) counting. Statistical model calculations taking into account precompound effects were performed for all the reactions studied. The experimental excitation functions are reproduced well by the calculation except for the (n,alpha) reaction on the (SC)-S-45 target.
