At the edge of nuclear stability: nonlinear quantum amplifiers
Attila Csoto, Heinz Oberhummer, Helmut Schlattl
We show that nuclei lying at the edge of stability can behave as nonlinear quantum amplifiers. A tiny change in the nucleon-nucleon interaction can trigger a much bigger change in…
Bridging the mass gaps at A=5 and A=8 in nucleosynthesis
Heinz Oberhummer, Attila Csoto, Helmut Schlattl
In nucleosynthesis three possible paths are known to bridge the mass gaps at A=5 and A=8. The primary path producing the bulk of the carbon in our Universe proceeds via the triple-…
On the Delta-Delta component of the deuteron in the relativistic field theory model of the deuteron
A. N. Ivanov, H. Oberhummer, N. I. Troitskaya +1
The Delta-Delta component of the deuteron, where Delta stands for the Delta(1232) resonance, is calculated in the relativistic field theory model of the deuteron. For the probabili…
Solar proton burning, neutrino disintegration of the deuteron and pep process in the relativistic field theory model of the deuteron
A. N. Ivanov, H. Oberhummer, N. I. Troitskaya +1
The astrophysical factor S_pp(0) for the solar proton burning, p + p -> D + positron + neutrino, is recalculated in the relativistic field theory model of the deuteron (RFMD). We o…
Neutron-proton radiative capture, photo-magnetic and anti-neutrino disintegration of the deuteron in the relativistic field theory model of the deuteron
A. N. Ivanov, H. Oberhummer, N. I. Troitskaya +1
The cross sections for the M1-capture n + p -> D + gamma, the photo-magnetic and anti-neutrino disintegration of the deuteron are evaluated in the relativistic field theory model o…
The relativistic field theory model of the deuteron from low-energy QCD
A. N. Ivanov, H. Oberhummer, N. I. Troitskaya +1
The relativistic field theory model of the deuteron (RFMD) is reformulated from the first principles of QCD. The deuteron appears as a neutron-proton collective excitation, i.e. a…
