Abstract
We found an error in our computation of the thermally averaged total rate coefficients for the collision of a room-temperature hydrogen dimer H$_2$ with an ultra-cold lithium sensor atom. We incorrectly accounted for the nuclear spin degeneracy and omitted the factor $1/\sqrt\pi}$ in the normalization over the Boltzmann distribution. Our corrected predictions for the thermally-averaged rate coefficient for a 300K H$_2$ gas and a 1$\mu$K Li gas are $3.13(6) \times 10^-9}$ cm$^3}$/s and $3.18(6) \times 10^-9}$ cm$^3}$/s for H$_2$+$^6$Li and H$_2$+$^7$Li, respectively, where the number in parenthesis is the one-standard-deviation uncertainty in the last significant digit. Moreover, the temperature dependence of the corrected rate coefficients near 300K is significantly smaller than in our original article.Citation
