For positive Q values, energy is released (exothermic) Fission Fusion n + 235 U --> 2n + 93 Rb + 141 Cs Q = 181 MeV 3 H(d,n) 4 He Q = 17.6 MeV For negative Q values, reaction threshold = -Q (endothermic) Pickup (n,2n) 208 Pb(p,d) 207 Pb Threshold = 5.17 MeV 179 Hf(n,2n) 180 Hf Threshold = 6.09 MeV
Rutherford Scattering Scattering from Coulomb field Differential cross section, σ R (θ), is forward peaked. Rutherford worked on 197 Au(α,α) 197 Au. Similar results for large enough charge or low enough energies. 208 Pb( 16 O, 16 O) 208 Pb
