Relative transition probabilities are measured for Co I and Co II, a gas-driven shock tube being used as the spectroscopic light source. Results for 139 Co I lines (3940<λ<6640 Å) and 11 Co II lines (3840<λ<4730 Å) are estimated to have reliabilities 8–50%. The results are compared with other experimental data.
