Abstract	A crossed beam scattering of a Pb(ZrxTi1-x)O₃plume and an oxygen jetwas studied by using a time-of-flight quadrupole mass spectroscopy. Both simple collisions and reactive scatterings had significant effects on the transportand energetics of ions in the plume. Relative enrichment of metal and metal oxide ions was also changed with the oxygen pulse because of the differences in the mass and chemical properties of the ions. In particular, an anomalous increase ofPb+ ions was observed as the oxygen jet crossed the plume at high laserfluences, while the signal magnitudes of alI other ions were reduced. This originates from the fact that PbO+ ions dissociate easily to liberate Pb+ ions inthe plume since the bond energy of PbO+ is as low as 2.2 eV.
