States of 12ΛC formed in the reaction 12C(K-, π-)

Abstract States of 12 Λ C formed in the (K − , π − ) reaction have been studied for momentum transfers up to 260 MeV/ c , using an incident K − beam of 800 MeV/ c momentum. The angular distributions for the g.s. and for a peak at 11 meV have been measured between 0° and 19° in the laboratory. Limits on the splitting of the 11 MeV peak and on the formation of low-lying excited states are given.
