    Calculations of the energy expended by a charged particle in producing optical excitation of molecules of the scintillator indicate the possibility that most of the energy emitted as light during a scintillation may stem, either directly or via intermolecular transfer, from molecules excited in this way. Observations of the slowly-decaying components of the emission suggest, however, that these co... View full abstract»

    Experimental studies of the response of thallium-activated alkali iodides to various charged particles indicate decreasing scintillation efficiency with increasing particle mass and a non-linearity in pulse height vs energy for heavier particles. The scintillation efficiency to electrons, however, is found to be anomalously low, less than that to protons and deuterons. This paper represents an eff... View full abstract»

    Observations of scintillation pulse heights have been made at pressures up to 75 atmospheres in xenon and argon, and in mixtures of nitrogen and xenon, nitrogen and argon, and neon and xenon. Diphenyl stilbene was used as a wavelength shifter. The most salient feature is that in all cases pulse height is approximately independent of pressure at pressures over a few atmospheres. The nitrogen-xenon ... View full abstract»

    A plastic scintillator has been developed which shows a decay time dependent upon energy loss per unit distance, and hence is suitable for use with pulse shape discrimination methods. This scintillator was employed in conjunction with an improved discrimination system and the data were analyzed on a two-dimensional analyzer which provided a matrix of 72 ?? 64 channels. At a bias level where 99 per... View full abstract»
