Abstract
We observe a splitting in the mass spectrum in interactions at . We find a mass of and a width of for the lower mass state, and a mass of 1344 ± 8 and a width of less than for the higher mass state. The isospin of both states is determined to be ½. The results can be interpreted as evidence for the mixing of two states.
