Neutron-induced background by an α-beam incident on a deuterium gas target and its implications for the study of the 2H(α,γ)6Li reaction at LUNA
The production of the stable isotope 6Li in standard Big Bang nucleosynthesis has recently attracted much interest. Recent observations in metal-poor stars suggest that a cosmological 6Li plateau may exist. If tr...

The definition of the effective interaction energy for astrophysical relevant reactions
Experimental studies of nuclear reactions of astrophysical interest are hampered by the exponential drop of the cross-section with decreasing energy. Generally, the effects of the projectile energy loss in the...

Towards a high-precision measurement of the 3He(α,γ)7Be cross section at LUNA
The 3He(4He,γ)7Be reaction is the key process for the production of 7Be and 8B neutrinos in the Sun. We have designed a new experimental setup to study this reaction with high accuracy at low energies using two d...

CNO hydrogen burning studied deep underground
In stars, four hydrogen nuclei are converted into a helium nucleus in two competing nuclear fusion processes, namely the proton-proton chain (p-p chain) and the carbon-nitrogen-oxygen (CNO) cycle. For temperat...
