Abstract
We have found an error in the computation of the thermally-averaged total elastic rate coefficient for the collision of a room-temperature helium atom with an ultra-cold lithium atom presented. We omitted the factor $2/\sqrt\pi}$ in the normalization over the Boltzmann distribution. Our corrected prediction for the thermally-averaged rate coefficient for a 300 K helium gas and a 1 $\mu$K Li gas is $1.655(15) \times 10^-9}$ cm$^3}$/s for $^4$He+$^6$Li and $1.659(15) \times 10^-9}$ cm$^3}$/s for $^4$He+$^7$Li, where the numbers in parenthesis are the one-standard-deviation uncertainties in the last two significant digits. The temperature dependence of the rate coefficients must be corrected with the same factor.Citation
