Enter The DRAGON: Investigating the 13C(p,g)14N reaction



The 13N(p,γ)14O reaction is very important for our understanding of explosive astrophysical sites, such as novae and supernovae. This reaction deter- mines the conditions under which the CNO cycle changes to the Hot CNO cycle, the main process of energy generation in such sites.

Since 13N is unstable, and is very close in mass to 13C, the DRAGON recoil mass separator at TRIUMF will firstly study the 13C(p,γ)14N reaction so that its properties can be compensated for when studying the 13N(p,γ)14O reaction.

Early analysis showed that not all the 14N recoils, from the 13C(p,γ)14N reaction, make it through the DRAGON to the end detector.
