Direct capture cross section of 9Be(n,γ)10Be: https://arxiv.org/abs/1904.12115

Peter Mohr

The cross section of the 9Be(n,γ)10Be reaction was calculated in the direct capture model. All parameters of the calculations were adjusted to properties of the 9Be + n system at thermal energies. The calculated cross section at thermonuclear energies shows the expected 1/v behavior of s-wave capture at low energies, but increases towards higher energies as typical p-wave capture. Excellent agreement between new experimental data in the astrophysically relevant energy region and the present calculation is found.
