We have measured the ɑ-particle spectrum from the decay of ^(16)N by selecting a low-energy ^(16)N beam with the TRIUMF isotope separator, TISOL, stopping the ^(16)N nuclei in a foil, and counting the α, particles and ^(12)C recoil nuclei, in coincidence, in thin surface-barrier detectors. The spectrum has been fitted by R- and K-matrix parametrizations which include the measured ^(12)C(α, y)^(16)O and ^(12)C(α,y)^(12)C cross sections. Best fit values for S_(E1)(0.3) have been derived for the El part of the ^(12)C(α,y)^(16)O reaction. These are S_(E1)(0.3)=75±20 keV·barn and S_(E1)(0.3)=62±15 keV·barn for the R- and K-matrix parametrizations, respectively.
