Carried by History: Cesar Lattes, Nuclear Emulsions, and the Discovery of the Pi-meson
@article{Vieira2014CarriedBH, title={Carried by History: Cesar Lattes, Nuclear Emulsions, and the Discovery of the Pi-meson}, author={C{\'a}ssio Leite Vieira and A.A.P Videira}, journal={Physics in Perspective}, year={2014}, volume={16}, pages={3-36} }
We analyze the role played by the Brazilian physicist Cesar Lattes (1924–2005) in the historical development of the nuclear emulsion technique and in the co-discovery of the pion. His works influenced and gave impetus to the development of experimental physics in Brazil, the foundation of a national center dedicated to physics research, the beginnings of Brazilian “Big Science,” and the inauguration of a long-lasting collaboration between Brazil and Japan in the field of comic ray physics.

Multiple Disintegration Processes Produced by Cosmic Rays
- PhysicsNature
- 1947
Experiments on the prototype of the new photographic emulsions for the detection of fast protons and other heavy particles, which are now being produced by Ilford, Ltd., in various types and which are referred to as ‘Nuclear Research Emulsions’, suggest they would be very suitable for detecting the multiple disintegration phenomena produced by the fast neutrons, γ-rays and other radiations in the cosmic rays.

The possibility of employing the nuclear reaction between boron and fast neutrons is examined, and the usual method, in which observations are made on the recoil protons which the neutrons produce by collision with hydrogen nuclei, is not applicable.
