Phys. Rev. Lett. 8 (1962) 175;

Motivation
In a previous Letter we reported a hydrogen-bubble-chamber experiment on the K^{-}p interaction in the vicinity of 400 MeV/c incident K^{-} momentum. The existence of an excited hyperon of 1520 MeV mass and 16 MeV full width was established; the state was found to have isotopic spin 0, spin 3/2, even parity with respect to K^{-}p, and a overline KN : :
2 branching ratio of 3:5:1. In this Letter we report the study of the angular distributions and polarizations of the different charge states, from which we conclude that the Kp parity is odd. (Extracted from the introductory part of the paper.).
