By K-matrix analysis of the ß -delayed spectrum of 16N it is possible to precisely measure the astrophysical S-factor at centre-of-mass energies around 300 keV, corresponding to a temperature of 1 billion Kelvins. An updated analysis of the data from the TISOL isotope separator is presented here. Using the TISOL data and the previous y-ray data, the K-matrix parameters have been simultaneously fitted, giving a value of S(E = 300 keV) = 83 ± 16 keV b for the El part of the 12C(a,y)16.vi, 44 pageselectronicen-CAhttp://purl.org/coar/access_right/c_16ecsenior reportDeMille, G.R.Physics
