Big Bang Cosmology in the Lab: The 2H(p,γ)3He reaction studied at LUNA


Big Bang Cosmology in the Lab: The 2H(p,γ)3He reaction studied at LUNA

Stöckel, K. For The Luna Collaboration

Recent high-precision measurements of the primordial 2H abundance have opened the path to use Big Bang nucleosynthesis to constrain the primordial baryon to photon ratio with similar precision as the cosmic microwave background. This would provide an independent cross-check on current Big Bang models. However, the interpretation of the abundance is limited by the lack of precise nuclear data, in particular on the main 2H destruction channel, the 2H(p,γ)3He reaction. A new experiment to study the 2H(p,γ)3He cross section directly in the Big Bang energy window is underway at the LUNA 400 kV accelerator, deep underground in the Gran Sasso laboratory, Italy. The progress of experiment and analysis will be summarized. – Supported by DFG (BE 4100/4-1).
