摘要：
This Letter presents a measurement of the decay τ-→ρ-ντ using data obtained with the Mark II detector at SPEAR. In the center-of-mass energy region 4.5<~Ec.m.<~6.0 GeV 85 events are observed in which a charged ρ was found in coincidence with either an electron or a muon. It was determined that B(τ-→ρ-ντ)=(20.5±4.1)% and the ratio B(τ-→ρ-ντ)B(τ-→e-ντν̄e)=1.11± 0.23. © 1979 The American Physical Society.
