Laboratory (LAB) angular and time-of-flight (TOF) recoil velocity spectra of SnO product produced by crossing a thermal Sn beam with an O/sub 2/ nozzle beam have been measured in a molecular beam apparatus equipped with an electron bombardment ionizer--quadrupole mass filter ''universal'' detector. Product center-of-mass (c.m.) recoil angle and energy distributions have been fit to the data by convoluting the c.m...-->..LAB transformation over the measured speed distributions in both beams and the instrumental TOF resolution. The results establish that the Sn+O/sub 2/ bimolecular reaction proceeds via formation of an osculating or long-lived SnO/sub 2/ collision intermediate. In addition, comparison of observed LAB product signals have established approximate relative total cross sections for reaction of Sn with O/sub 2/, CO/sub 2/, SO/sub 2/, N/sub 2/O, CH/sub 3/OH, and CH/sub 3/NO/sub 2/.
