A New 13N(p,γ)14O Reaction Rate And Its Influence In Novae Nucleosynthesis

摘要

The direct capture contribution for 13N(p,γ)14O has been determined more precisely with the peripheral transfer reaction, 14N(13N,14O)13C at the energy of 11.8 MeV/nucleon using the ANC technique. The updated 13N(p,γ)14O reaction rate is about 2.5 times larger than the standard REACLIB rate in the temperature range 0.1 < T9 < 0.3. The transition condition from the cold to hot CNO cycles has been determined with this updated rate. The influences incurred by this update have been investigated with two one-zone nova models.
