| Abstract: | YBa2Cu307 target was laser ablated, and the time-of-flight (TOF) distributions of Y, Y+., and YO in
the resultant plasma were investigated as functions of distance from the target and laser energy
density using emission spectroscopy. Up to a short distance from the target (-1.5 cm), TOF
distributions show twin peaks for Y and YO, while only single-peak distribution is observed for Y+.
At greater distances (>1.5 cm) all of them exhibit single-peak distribution. The twin peaks are
assigned to species corresponding to those generated directly/m the vicinity of target surface and to
those generated from collisional/recombination process. |
