Background: The ²²Ne(α,n) ²⁵Mg reaction is the dominant neutron source for the slow neutron capture process (s process) in massive stars, and contributes, together with C¹³(α,n)O¹⁶, to the production of neutrons for the s process in asymptotic giant... Read More

Constraining the 12C+12C fusion cross section for astrophysics (2015)
Journal Article
Bucher, B., Fang, X., Tang, X., Tan, W., Almaraz-Calderon, S., Alongi, A., …Wiescher, M. (2015). Constraining the 12C+12C fusion cross section for astrophysics. EPJ Web of Conferences, 93, 03009. doi:10.1051/epjconf/20159303009

The 12 C+ 12 C reaction is one of the single most important nuclear reactions in astrophysics. It strongly influences late evolution of massive stars as well as the dynamics of type Ia supernovae and x-ray superbursts. An accurate estimation of the c... Read More
