With the advent of the Geiger-Muller counter in the late 1920s, the nature of cosmic rays became accessible to exper- imentation. When used single as cosmic-ray detectors, these devices did not have significant advantages over ionization chambers. They became a powerful new tool for cosmic-ray experiments when used in coincidence arrangements. The coincidence technique, first used by Hans Geiger and Walther Bothe in 1924 to verify that Compton scattering produces a recoil electron…

From cosmic ray physics to cosmic ray astronomy: Bruno Rossi and the opening of new windows on the universe
Bruno Rossi is considered one of the fathers of modern physics, being also a pioneer in virtually every aspect of what is today called high-energy astrophysics. At the beginning of 1930s he was the
International Scientific Cooperation During the 1930s. Bruno Rossi and the Development of the Status of Cosmic Rays into a Branch of Physics
TLDR
A glimpse of the intersection between national and international dimensions during the 1930s is provided, at a time when the study of cosmic rays was still very much in its infancy, strongly interlaced with nuclear physics, and full of uncertain, contradictory, and puzzling results.
Photon-electron coincidence experiments at synchrotron radiation facilities with arbitrary bunch modes.
TLDR
The adaptation of an electron-photon coincidence detection scheme to the multibunch hybrid mode of the synchrotron radiation source BESSY II (Helmholtz-Zentrum Berlin) is reported, expecting this method to be a useful tool to extend the versatility of coincident particle detection to arbitrary operation modes ofsynchrotrons radiation facilities and other excitation sources without the need for additional experimental adjustments.
Theoretical formula for the cosmic-ray muon attenuation coefficients of Pb, Cu, Zn, and Al
ABSTRACT The attenuation coefficients of cosmic-ray muons through metal plates were theoretically determined. Three methods (A, B, and C) were proposed by the researchers using the experimental data
Lo spirito di Arcetri
On 7 November 1921, the new Institute of Physics of the Royal Institute of Higher, Practical and Advanced Studies of Florence was inaugurated in Arcetri. Three years later, with the establishment of
Investigation of Simple Portable Telescope Validity for Muon Detection Inside Metals
Muons produced in the atmosphere by cosmic rays are preferred over gamma rays, X-rays and fast protons for the detection of metals in the study of radiography. An alternative method for metals
Enrico Fermi’s Discovery of Neutron-Induced Artificial Radioactivity: A Case of “Emanation” from “Divine Providence”
We reconstruct Enrico Fermi’s remarkable discovery of neutron-induced radioactivity in March 1934 with a focus on the experimental apparatus he used, such as the original neutron sources preserved in
Trace element analysis based on neutron activation with coincident gamma ray detection
In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of
Electron Scattering Processes in Non-Monochromatic and Relativistically Intense Laser Fields
The theoretical analysis of four fundamental laser-assisted non-linear scattering processes are summarized in this review. Our attention is focused on Thomson, Compton, Møller and Mott scattering in
