First direct measurement of<sup>12</sup>C(<sup>12</sup>C,n)<sup>23</sup>Mg at stellar energies
Neutrons produced by the carbon fusion reaction 12 C( 12 C,n) 23 Mg play an important role in stellar nucleosynthesis.Past studies have shown large discrepancies between experimental data and theory, leading to an uncertain cross section extrapolation at astrophysical energies.We present the first direct measurement which extends deep into the …
