The result on λ-rays obtained from the analysis of 5800 orbits of data from the University of Rochester telescope on board the OSO-3 satellite are presented. For γ-rays of energy greater than 100 MeV, an upper limit of 2.3×10−4 cm−2 s−1 std

A number of investigations have recently been carried out to measure the isotopic composition of primary helium nuclei. The composition observed is modified from its true composition at the source (s) by its passage through interstellar hydrogen, owi

The primary cosmic-rayα-particle energy spectrum has been investigated, using photographic emulsions flown from Minneapolis on July 30th, 1957. The total flux observed was (151±9)particles/cm2 sr s. The differential energy spectrum shows a broad ma

The response of the plastic scintillator1) NE102 to cosmic ray particles has been determined during two balloon flights of a double ( d E d x ) E counter telescope from Fort Churchill, Canada in July and August 1966. The results have been fitted to a

A discussion is given of the procedures employed in the analysis of primary cosmic ray intensity experiments and the assumptions inherent in their use, with particular emphasis on nuclear emulsion as a detector. Explicit formulae for extrapolation of

The maximum often observed at low energies in primary cosmic ray spectra is examined with respect to the possible effect of isotopic composition. It is shown that a maximum can arise if He/sup 3/ and He/sup 4/ are not distinguished and spectra are pl

The photon-nucleon production of $\ensuremath{\pi}$-mesons has been calculated incorporating in the interaction a Pauli-type term representing the interaction of the photon with the anomalous magnetic moments of the nucleons. The effect of the added

Techniques have been developed by which the energy spectrum of heavy primary nuclei can be measured in the energy range of ${10}^{9}$-${10}^{11}$ ev/nucleon and of both protons and $\ensuremath{\alpha}$-particles in the energy range from ${10}^{11}$
