1949 Nature 15 Jan. 85/2 The agreement between the sets of values for mesons..gives strong support for the assumption of a spontaneous decay of the k-particle.

1954 Proc. Royal Soc. A. 221 293 Those charged particles more massive than the π-meson which, at the end of their range in the emulsion, transmute with the emission of a singly-charged particle, are referred to as K-particles... The charged particles are in some cases μ-mesons, and others π-mesons.

1955 Sci. News Let. 19 Feb. 117/2 K particles are mesons of mass intermediate between electrons and protons.

1966 D. L. Livesey Atomic & Nucl. Physics x. 468 The neutral K particle must therefore possess a rest mass greater than 550 m_e, the measured energy release being such that the calculated mass is about 1000 m_e.
