Abstract

Physical review letters 58(10), 972 - 975 (1987). doi:10.1103/PhysRevLett.58.972, Angular correlations in the cascade reaction e+e−→Υ(2S)→γχb, χb→γΥ, Υ→μ+μ− or Υ→e+e−, have been used for the first time to investigate the spins of the χb states. The results support the χb spins predicted by the potential models of heavy quarkonia., Published by APS, College Park, Md.
