The first low-temperature (<4 K) determination of the sticking probability S of a He4 atom on a solid surface is presented. It is found that 23S<1 for a thermal distribution of incident atoms with beam temperature 10 to 20 K. This result is not affected by the presence of a preadsorbed, 1-monolayer He film.
