ABSTRACT
Investigates the time-of-flight distributions of yttrium (Y), Y[sup +], and yttrium oxide in laser ablated plasma from YBa[sub 2]Cu[sub 3]O[sub 7]. Observation of twin-peak structure for atomic and molecular species at short distances; Factor causing the appearance of the delayed component; Effect of the species created by recombination process on the first peak.
