Cloud chamber study of cosmic-ray particles
<p>In order to study the energy loss of cosmic-ray electrons in light materials where inelastic atomic collisions account for the main part of the loss, 10,000 cloud chamber photographs were taken in which a thin-walled copper counter or a combination of one or two counters with a 1/4 inch...
