    Notes: [Auszug] RECENT evidence1, 2 of neutral particles of atomic mass and great penetrating power suggests the possibility that terrestial matter may contain similar particles of low (thermal) energies, undetected hitherto by reason of their small interaction with matter. While it has been ...

    Notes: [Auszug] DURING the past decade, several phenomena that had previously been observed with light or with X-rays have been studied with nuclear y-rays, where the quantum energy is typically 100 keV.-10 MeV. and the wave-length correspondingly short, 10~9 to 10~n cm. Some new phenomena, specifically nuclear or ...

    Notes: [Auszug] Coherence may be experimentally proved by observing interference between the resonance radiation and some other form of scattering that is known to be coherent ; for y-rays, one would naturally look for interference with the Rayleigh (elastic electronic) scattering. In the long-studied 411 keV. ...

    Notes: [Auszug] IN our letter of April 121, we mentioned that the absorption of slow neutrons by iodine was apparently greater when the induced (β-ray activity of an iodine detector was used as a measure of the number of neutrons transmitted than when detectors of silver or rhodium were ...

    Notes: [Auszug] WE have searched in a number of ways for experimental evidence of the existence of neutrons of thermal energies, using a radon-beryllium source of fast neutrons and allowing them to diffuse through materials rich in hydrogen1. Until very recently we could find no such evidence, ...

    Notes: [Auszug] WE have been developing during the past year an apparatus to make possible the study of neutrons of known energies within the thermal region. In principle, the apparatus consists of a device for producing a burst of neutrons lasting about 0.5 millisecond at intervals of 5 milliseconds. The ...
