High statistics data for the reaction K −p→K −π +n at 11 GeV/ c have been obtained in the LASS spectrometer at SLAC. A spherical harmonic moments analysis provides clear evidence for the production of the complete leading orbitally excited K ∗ series up through J P = 5 −. New measurements are made of the masses and widths of the 1 −K ∗(892), 2 +K ∗(1430 ), 3 − K ∗(1780), and 4 + K ∗(2060), and evidence is presented for the production of a new K ∗ state at 2382 MeV/ c 2 with spin-parity 5 −.
