/* Experimental Method:
- Beam current integrated (Beam currents were monitored with a
Faraday cup connected to a current integrator.)
- Activation (Proton bombardments were carried out with the
incident energies of 20 and 13 MeV for 1 to 1.5 hour to ensure
production of sufficient activities of fission products.)
- Gamma ray spectrometry (Formation cross sections of each
nuclide were determined by gamma-ray spectrometry, The nuclear
properties of fission products used in this work are listed in
Table 1.)
