Table 3.

For different neutron producing reactions the table lists the threshold and some bombarding energies, the corresponding total thick target neutron production, the percentage for which the maximum neutron energy is less than 1 MeV, and the maximum and minimum neutron energies (14Colonna et al. 1999). For the 7Li(p,n)7Be reaction, En,max and En,min correspond to ⁷Be in its ground state.
