Measurements of the neutron spectrum from the T(t,2n)4He (tt) reaction have been conducted using inertial confinement fusion implosions at the OMEGA laser facility. In these experiments, deuterium-tritium (DT) gas-filled capsules were imploded to study the tt reaction in thermonuclear plasmas at low reactant center-of-mass (c.m.) energies. In contrast to accelerator experiments at higher c.m. e...
The radiative neutron capture reaction rates have been studied at very low energies which are of interest for nuclear astrophysics. many these reactions remained independent temperature so far. dependence the thermonuclear explored within statistical model. Apart from compound contribution, pre-equilibrium as well direct effects taken into account. corresponding Maxwellian-averaged relevance in...
We demonstrate that the cross sections derived from the " shadow model " for reactions between light nuclei disagree with low–energy laboratory data and exhibit unphysical behavior at energies below those for which data exist. As a consequence, the large thermonuclear reaction rates obtained by Scalia and Figuera [Phys. Rev.
The theoretical predictions of big bang nucleosynthesis (BBN) are dominated by uncertainties in the input nuclear reaction cross sections. In this paper, we examine the impact on BBN of the recent compilation of nuclear data and thermonuclear reactions rates by the NACRE collaboration. We confirm that the adopted rates do not make large overall changes in central values of predictions, but do a...
