We have studied the ejecta produced by the normal incidence impact at 5 km s(-1) of I mm diameter stainless steel spheres on CO2 ice. The ejecta size and angle of ejection were measured by use of thin witness foils. We reconstruct the size distribution (for angles between 20 degrees and 80 degrees to the ice surface) and find it is dependent on angle of ejection. Between angles of ejection of 20 degrees and 80 degrees; we find that the measured ejected mass flow is maximum at (62.5 +/- 2.5)degrees, and represents approximately 1.4 % of the crater mass.
