An effective field theory technique that combines the standard nuclear physics approach and chiral perturbation theory is applied to the hen process, 3He+n→ 4He+ γ. For the initial and final nuclear states, high-precision wave functions are generated via the variational Monte Carlo method using the Argonne v14 potential and Urbana VIII trinucleon interactions, while the relevant transition operators are calculated up to \cal O(Q4) in HBχPT. The imposition of the renormalization condition that the magnetic moments of 3He and 3H be reproduced allows us to carry out a parameter-free calculation of the hen cross section. The result, σ=(60± 3± 1) μb, is in reasonable agreement with the experimental values, (54± 6) μb and (55± 3) μb. This agreement demonstrates the validity of the calculational method previously used for estimating the reaction rate of the solar hep process.
