The properties of jets produced in e/sup +/e/sup -/ annihilation have been investigated using data taken with the Mark 1 detector at SPEAR. The momentum distributions parallel and perpendicular to the jet axis were measured for all charged tracks, for K/sup 0/'s, and for rho/sup 0/'s. The K/sup 0/ and rho/sup 0/ Pt/sup 2/ distributions are well fit by the form dn/dPt/sup 2/ = A exp(-B/sup +/ Pt/sup 2/) with B = 4.6 +/- 0.2 for K/sup 0/'s and 5 +/- 1 for rho/sup 0/'s. The charged particle Pt/sup 2/ distribution cannot be fit with a single exponential, but is similar to that of K/sup 0/'s and rho/sup 0/'s above Pt/sup 2/ approx. 0.2 GeV/sup 2/. The charged particle and K/sup 0/ parallel momentum distributions are similar in shape and approximately exponential. The production of rho/sup 0/'s at low parallel momentum is suppressed. The average number of rho/sup 0/'s per event is 0.4 +/- 0.1. 59 figures, 7 tables.
