Study of the 2H(p,γ)3He reaction in the Big Bang Nucleosynthesis energy range at LUNA

Deuterium is the first nucleus produced in the Universe, whose accumulation marks the beginning of the so called Big Bang Nucleosynthesis (BBN). Its primordial abundance is very sensitive to some cosmological parameters like the baryon density and the number of the neutrino families. Presently the m...
