For exothermic, threshold is 0 if no barrier. But in nuclear physics, threshold often means including conservation of momentum. Actually, the formula: [ K_{\text{th}} = -Q \frac{m_{\text{target}} + m_{\text{projectile}}}{m_{\text{target}}} \quad \text{(for endothermic reactions)} ] For exothermic (Q>0), threshold is 0 in CM frame. In lab, minimal projectile energy >0 because of recoil? No — if Q>0, reaction can occur even at very low energy, limited only by Coulomb barrier. David Halliday , widely known for Fundamentals of
