  The cross section of the $^{9}$Be(n,$\gamma$)$^{10}$Be reaction was
calculated in the direct capture model. All parameters of the calculations were
adjusted to properties of the $^{9}$Be + 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.
