Primordial and Pre-Galactic Origins of the Lithium Isotopes
There are currently two cosmological lithium problems: compared with predictions from Big Bang Nucleosynthesis and models for Galactic cosmic ray production, the observed 7Li abundance in Galactic hal...

Feedback From the First Stars and Galaxies and its Influence on Structure Formation
Once the first sources have formed, their mass deposition, energy injection and emitted radiation can deeply affect the subsequent galaxy formation process and influence the evolution of the IGM via a...

The reaction cross section for the direct radiative proton capture on the the drip line nucleus 12N—12N(p,)13O—was studied at the Cyclotron Institute/Texas A&M University using the indirect asymptotic normalization coefficient method. This reaction is important in the hot pp chain nuclear burning processes in hydrogen-rich massive objects (Population III stars). The astrophysical S-factor of the direct proton capture was determined at zero energy yielding a value of S
= 0.31(5) keV b. Interference between direct and resonant capture leads to a further enhancement of a factor of two.
