Neutron capture excitation functions

Figure 5. Preliminary calculations of the neutron capture excitation functions for the 204Bi-210Bi targets.

Two other important features of Figure 14.1 deserve further comment. The first of these features is the large difference between the excitation functions for (n, f) reac-tions with U and U. We can understand this difference by noting the Q values for neutron capture by these nuclides are... 

Left Schematic representation of the excitation function for the capture of neutrons in a (n, ) reaction. In this figure the velocity of the neutron is indicated by u. Right Total cross section dependence on bombarding energy per nucleon for a charged-particle reaction...
