TL;DR: In this article, a total of 3,480 K/sup -/-mesons were observed, of which 445 interact in flight, at a mean energy of 40 Mev and only their general characteristics were studied.

TL;DR: In this article, a large emulsion stack, exposed at high altitude, has been used to study the decaymodes of K-particles which produce a single charged secondary.

LXI. On the mass of the Λ0-particle
TL;DR: In a stack of stripped photographic emulsions, twenty events of type 2+0 n have been observed, in each of which the outgoing particles are a proton and a negative π-meson respectively; the latter particle was identified by the characteristic star it produced when brought to rest in the emulsion.

CXV. Evidence for the β-decay of a K-meson
TL;DR: In this article, the decay at rest of a K-meson in which the secondary particle appears to be an electron of ∼90mev has been observed, and the most plausible explanation of this behaviour is due to the sudden loss of energy of an electron through the production of bremsstrahlung.

Hyperon events in photographic emulsions
TL;DR: In this article, the authors describe six hyperon events observed in photographic emulsions and give Q-values of 115.8±1.0 MeV and 113.5± 1.7 MeV for the assumed decay scheme: Y+ → p+π0+Q.
