We present results on the jet structure observed in multi-hadronic events produced by e+e-annihilation in the Mark I magnetic detector at SPEAR. The evidence for jet structure and the jet axis angular di.stribution are reported. We give inclusive distributions of the hadrons in Feynman x, rapidity, and transverse momentum relative to the jet axis.
Classical collisions with an ideal gas generate non-Maxwellian distribution functions for a single ion in a radio frequency ion trap. The distributions have power-law tails whose exponent depends on the ratio of buffer gas to ion mass. This provides a statistical explanation for the previously observed transition from cooling to heating. Monte Carlo results… (More)
