How Well Do We Know the Beta-Decay of N16 and Oxygen Formation in Helium Burning?

Contrary to claims that the problem has been solved, the astrophysical E1 S-factor of 12ag is not yet well known. R-Matrix analyses of elastic scattering data,12ag data, and data on the beta-delayed alpha-particle emission of N16 are not consistent and a small S-factor solution SE1(300) cannot be ruled out. In particular, data on the beta- delayed alpha-particle emission of N16 do not agree. The unaltered Mainz data do not agree with TRIUMF, but agree with both Seattle and Yale-UConn. The TRIUMF col- laboration has recalibratedthe Mainz('71) data; however, we dispute both the alteration of the Mainz data performed by the TRIUMF col- laboration and the very justification for the recalibration.
