Opportunities to constrain astrophysical reaction rates for the s-process through determination of the ground state cross sections
nuclear reactions nucleosynthesis abundances
2011/7/21
Modern models of s-process nucleosynthesis in stars require stellar reaction rates with high precision. Most of the neutron capture cross sections in the s-process have been measured and for an increa...

Constraining the S factor of 15N(p,g)16O Astrophysical Energies
2011/1/4
The 15N(p,g)16O reaction represents a break out reaction linking the first and second cycle of the CNO cycles redistributing the carbon and nitrogen abundances into the oxygen range. The reaction is d...
Study of Proton Resonances in 22Mg by Resonant Elastic Scattering of 21Na+p and Its Astrophysical Implication

2009/10/29
Proton resonant states in 22Mg have been investigated by the resonant elastic scattering of 21Na+p. The 21Na beam with a mean energy of 4.00 MeV/u was separated by the CNS radioactive ion beam separat...
