Large-space cluster model calculations for the 3He(3He,2p)4He and 3H(3H,2n)4He reactions
The 3He(3He, 2p)4He and 3H(3H, 2n)4He reactions are studied in a microscopic cluster model. We search for resonances in the 3He+3He and 4He+p+p channels using methods that treat the twoand three-body resonance asymptotics correctly. Our results show that the existence of a low-energy resonance or virtual state, which could influence the 7Be and 8B solar neutrino fluxes, is rather unlikely. Our ...
متن کاملNeutron–3H and Proton–3He Zero Energy Scattering
The Kohn variational principle and the (correlated) Hyperspherical Harmonics technique are applied to study the n − 3H and p − 3He scattering at zero energy. Predictions for the singlet and triplet scattering lengths are obtained for non–relativistic nuclear Hamiltonians including two– and three– body potentials. The calculated n−3H total cross section agrees well with the measured value, while...
متن کاملDemonstrating trend reversal of groundwater quality in relation to time of recharge determined by 3H/3He.
Recent EU legislation is directed to reverse the upward trends in the concentrations of agricultural pollutants in groundwater. However, uncertainty of the groundwater travel time towards the screens of the groundwater quality monitoring networks complicates the demonstration of trend reversal. We investigated whether trend reversal can be demonstrated by relating concentrations of pollutants i...
متن کاملInclusive electron scattering on 3H and 3He with full inclusion of final state interactions.
InClusive electron scattering data on 3He and 3H are analyzed under full treatment of the final state interactions (FSI) using realistic nucleon-nucleon forces. The data are well described. We use two different methods, one where we calculate the pd and ppn breakup contributions separately and another one which is related to the optical theorem for Compton scattering. Both rely on precise solut...
متن کامل3H/3He Squeeze-Out - A Signature of the Fireball’s Isospin Distribution?
The Phase I FOPI data evidence for highly central Au + Au collisions at 100, 150 and 250 A·MeV systematically larger mean kinetic energies for He fragments relative to the H values [1]. The EOS Collaboration find the same trend with somewhat larger size [2]. Microscopic transport models [3] and hybrid hydrodynamical models, including pure Coulomb repulsion at the freeze-out moment [4] do not su...
