Extracting the Asymptotic Normalization Coefficients in Neutron Transfer Reactions to Determine the Astrophysical Reaction Rates for 22Mg(p,
)23Al and 17F(p,)18Ne
It was expected that rays from 18F and 22Na would be observed in massive One novae, but neither has been to date. The 17F(p,)18Ne and 22Mg(p,)23Al reactions may play important roles in the production...

Secondary Cosmic Ray Particles due to GCR Interactions in the Earth's Atmosphere
Primary GCR interact with the Earth's atmosphere originating atmospheric showers, thus giving rise to fluxes of secondary particles in the atmosphere. Electromagnetic and hadronic interactions interpl...

The reaction cross section of the radiative proton capture on the drip line nucleus 12N was studied at the Cyclotron Institute at Texas A&M University. We have employed the indirect Asymptotic Normalization Coefficient method to determine the direct radiative component of the astrophysical S-factor of the 12N(p,)13O reaction. A value of 0.31(5) keV·b was found at zero energy. Interference between direct and resonant captures leads to a further enhancement of a factor of two. The reaction was investigated in relation to the evolution of hydrogen-rich massive objects, Population III stars, because of the role that it may play in the hot pp chain nuclear burning processes occurring in such stars.
