Field theory of the d + t → n + α reaction dominated by a ⁵He^* unstable particle

NUCLEAR REACTIONS ³H(d, n)⁴He, E(cm)<0.10 MeV; analyzed astrophysical S(E) factor from a fit of 2665 experimental data points. Effective, nonrelativistic quantum field theory method providing a description of the d+t fusion process, with the assumption that an intermediate ⁵He* unstable spin-3/2+ resonance dominates the d+t-fusion reaction.
