Systematic study of (n,p) reaction cross sections from the reaction threshold to 20 MeV (original) (raw)

The cross sections of nat Cr(n,x) 52 V, 52 Cr(n,p) 52 V, nat Cr(n,x) 53 V, 53 Cr(n,p) 53 V, nat Zn(n,x) 66 Cu, 66 Zn(n,p) 66 Cu, nat Zn(n,x) 68 Cu m , 68 Zn(n,p) 68 Cu m , nat Mo(n,x) 97 Nb g , 97 Mo(n,p) 97 Nb g , nat Mo(n,x) 97 Nb m , 97 Mo(n,p) 97 Nb m , nat Sn(n,x) 116 In m1+m2 , 116 Sn(n,p) 116 In m1+m2 , nat Sn(n,x) 117 In g , 117 Sn(n,p) 117 In g , nat Sn(n,x) 118 In m1+m2 , 118 Sn(n,p) 118 In m1+m2 , nat Sn(n,x) 120 In x , 120 Sn(n,p) 120 In x , nat Ba(n,x) 138 Cs, and 138 Ba(n,p) 138 Cs reactions have been measured at 14.8 MeV neutron energy. In the present work, the contributions of (n,np), (n,pn), and (n,d) reactions from heavier isotopes are subtracted. The cross sections were also estimated with the TALYS-1.2 nuclear model code using different level density models, at neutron energies varying from the reaction threshold to 20 MeV. The variations in the (n,p) cross sections with the neutron number in the isotopes of an element are also discussed in brief.
