1949Nature 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. 1954Proc. R. Soc. A. CCXXI. 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. 1955Sci. News Let. 19 Feb. 117/2 K particles are mesons of mass intermediate between electrons and protons. 1966D. L. Livesey Atomic & Nucl. Physics x. 468 The neutral K particle must therefore possess a rest mass greater than 550 me, the measured energy release being such that the calculated mass is about 1000 me. |
