High resolution kinematics of galactic globular clusters. I.

We present integrated central velocity dispersions for 7 globular clusters, three of which known to be post core-collapsed. Discussion of the statistical significance of the measurements is presented. For one of the clusters, M30, we also provide radial velocities of 16 stars, which help mapping the inner velocity dispersion profile. Our data suggest that M30 has more likely an isothermal core, at variance with the behavior of its closest twin M15.
