The currently favored {ital s} process scenario of helium shell burning in low mass stars involves a range of thermal energies from {ital kT}=12 to 25 keV with most of the neutron exposure taking place at low temperatures. Therefore, differential cross sections are required down to the region of resolved resonances for the reliable determination of the Maxwellian-averaged cross sections typical of the stellar plasma. This work deals with the neutron capture cross sections of the important {ital s} only isotopes {sup 122}Te, {sup 123}Te, and {sup 124}Te, which were measured between 1 and 60 keV neutron energy with a setup of Moxon-Rae detectors. The systematic uncertainties achieved in this experiment are {similar to}5%, but statistical uncertainties are smaller than 2%. In addition to the Moxon-Rae detectors, the setup includes a {sup 6}Li glass detector which could be used to determine the total neutron cross sections simultaneously. These results represent the first set of experimental data in this energy range.
