In a recent paper, we have used the dark-spot Zeeman tuned slowing technique[Phys. Rev. A 62, 013404-1, (2000)] to measure the capture velocity as afunction of laser intensity for a sodium magneto optical trap. Due to technicallimitation we explored only the low light intensity regime, from 0 to 27mW/cm^2. Now we complement that work measuring the capture velocity in abroader range of light intensities (from 0 to 400 mW/cm^2). New features,observed in this range, are important to understant the escape velocitybehavior, which has been intensively used in the interpretation of coldcollisions. In particular, we show in this brief report that the capturevelocity has a maximum as function of the trap laser intensity, which wouldimply a minimum in the trap loss rates.Comment: 2 pages, 2 figure
