Processes Involving Charged Mesons

  title={Processes Involving Charged Mesons},
  author={Cesare Mansueto Giulio Lattes and Hilary Muirhead and Giuseppe Paolo Stanislao Occhialini and Cecil Frank Powell},
In recent investigations with the photographic method1,2, it has been shown that slow charged particles of small mass, present as a component of the cosmic radiation at high altitudes, can enter nuclei and produce disintegrations with the emission of heavy particles. It is convenient to apply the term ‘meson’ to any particle with a mass intermediate between that of a proton and an electron. In continuing our experiments we have found evidence of mesons which, at the end of their range, produce… Expand
Observations on the Production of Mesons by Cosmic Radiation
It is shown that at least the majority of the ‘ejected' mesons observed interact with nuclei and are therefore negatively charged; and that on the average they produce more vigorous nuclear disintegrations than most of the negative mesons which stop in the emulsions after being generated outside it.

Meson Decay and the Theory of Nuclear Forces
IN recent observations with the photographic plate method, Lattes, Muirhead, Occhialini and Powell1 have given direct evidence of cosmic ray mesons with two different masses; furthermore, in some ofExpand
Determination of the masses of charged particles observed in the photographic plate
A study has been made of scattering of 40 protons and 160 mesons in photographic emulsions in order to determine the mass of the individual particles. The spread in the values so obtained is large,Expand
The Artificial Production of Mesons
Most of the experiments have been made by the bombardment of carbon ; but in similar conditions, targets of beryllium, copper and uranium yield mesons in approximately the same numbers. Expand
FROM PIONS TO PROTON DECAY: Tales of the Unexpected
▪ Abstract This account recalls early observations of elementary particles from cosmic ray experiments, using the nuclear emulsion technique. Discoveries in this field in the 1940s and 50s led to theExpand
Threshold pion photoproduction on nucleons
Pion photo- and electroproduction of the nucleon at threshold is reviewed in theory and experiment. In this region the leading S-wave amplitudes (E0+) are predicted by low-energy theorems (LET) basedExpand
Laser spectroscopy of pionic helium atoms
Long-lived pionic helium atoms (composed of a helium-4 nucleus, an electron and a negatively charged pion) are synthesized in a superfluid-helium target, as confirmed by laser spectroscopy involving the pion-occupied orbitals. Expand
Production of light neutral mesons in the ALICE experiment at the LHC
Light pseudo-scalar neutral mesons have been studied in e+e−, hadron-hadron, hadron-nucleus and nuclear collisions for decades. The results associated with neutral mesons provide information that isExpand
Exclusive Scattering off the Deuteron
Exclusive processes are a special class of processes giving insight into the inner structure of hadrons. In this thesis we consider two exclusive processes and compute their total cross sections asExpand
Parton models of low momentum transfer processes
In the last five years ample evidence has been found supporting the idea that the quark-parton structure of hadrons is relevant for multiple production in soft hadronic collisions. Starting from theExpand


Nuclear Disintegration by Meson Capture
Whereas all stars previously observed had been initiated by radiation not producing ionizing tracks in the emulsion, the one in question appears to be due to nuclear capture of a charged particle, presumably a slow meson. Expand
An Example of Meson Production in Lead
WE have recently obtained a clear example of meson production in lead in an experiment in which counter-controlled, cloud-chamber photographs of penetrating showers were taken in a magnetic field ofExpand
Nuclear Disintegrations Produced by Slow Charged Particles of Small Mass
IN studying photographic plates exposed to the cosmic rays, we have found a number of multiple disintegrations each of which appears to have been produced by the entry of a slow charged particle intoExpand
The Decay of Negative Mesotrons in Matter
. disintegration electrons are observed only for positive mesotrons. This was indeed to be expected' because negative mesotrons after being slowed down can approach the nuclei and disappear byExpand
A Photographic Method of Estimating the Mass of the Mesotron
IN a communication in NATURE1 it was concluded that the heavy ionization tracks found in Ilford New Halftone plates kept exposed to cosmic rays at Sandakphu (12,000 ft.) were chiefly due toExpand
