Abstract: (APS)

The 18Ne(α,p)21Na reaction is one key for the breakout from the hot CNO cycles to the rp-process. Recent papers have provided reaction rate factors NA〈σv〉 which are discrepant by at least one order of magnitude. The compatibility of the latest experimental results is tested, and a partial explanation for the discrepant NA〈σv〉 is given. A new rate factor is derived from the combined analysis of all available data. The new rate factor is located slightly below the higher rate factor found by Matic [Phys. Rev. CPRVCAN0556-281310.1103/PhysRevC.80.055804 80, 055804 (2009)] at low temperatures and significantly below at higher temperatures whereas it is about a factor of 5 higher than the lower rate factor recently published by Salter [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.108.242701 108, 242701 (2012)].
