We observe the production of Na[sup +] ions in a single effusive sodium atomic beam via intrabeam dissociating collisions of laser-excited Na(3[ital p]) atoms with Na[sub 2][sup +] ions created by associative ionization. The rather large cross section for this collisional dissociation process has been experimentally determined to be 3([plus minus]1)[times]10[sup [minus]13] cm[sup 2] at a source temperature of [approx]530 K. A classical Langevin model gives an estimate based on long-range forces of about twice this value.
