Study of the Bi209 (gamma,pi-xn) Po209-x and Pb206 (He3,xn) Po209-x reactions by detection of polonium alpha activities
… been measured for a complex nucleus. At bremsstrahlung energies of 200,220, and 250 MeV, the total cross sections are 0.79 2.89 and 8.9 mb, respectively. These are 6.5, 24 and 65 times the CGLN cross sections for (gamma, pi-) on free neutrons. This result disagrees with both surface …
