We present a study of newly identified cometary globules in the south-east quadrant of the Rosette nebula using the J=1-0 transition of carbon monoxide. The observations were made using the FCRAO 14m telescope with the QUARRY receiver. The emission from the globules is found to be blue-shifted by about 6; km; s(-1) , with respect to that from the adjacent Rosette molecular cloud, in agreement with the value predicted by the rocket effect. The masses of the globules vary from 50 to 300 M_&sun;, and their sizes are between 1 and 3 pc. Two of the globules have cometary morphology and show velocity gradients of ~ 1.5; km; s(-1) ; pc(-1) along their symmetry axes. These globules themselves are associated with the IRAS sources 06314+0421, X0632+043, 06322+0427 and 06327+0423 which coincide with local maxima in the (13) CO emission. This suggests that star formation induced by radiation driven implosion has occurred. The derived physical parameters of the globules are found to be consistent with those predicted by recent theoretical models of photo-evaporating cometary clouds.
