dc.description.abstract | The rate of 12C(a,y)16O reaction that occurs in helium burning stars is critical to the evolution of stars over twenty-five solar masses. 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. | |
