|Title:||INCIDENT ANGLE DEPENDENCE OF PHOTOGRAPHIC DARKNESS ON X-RAY-FILMS EXPOSED IN EMULSION CHAMBERS|
|Abstract:||X-ray films of two different grain sizes have been exposed to the electron beam of an accelerator at different incident zenith angles with the aim of studying the influence of the angle on the measured optical density of the spot left by the beam on the films. Such study is motivated by the need to use optical means in the energy measurement of eletromagnetic showers in high energy collision events detected in emulsion chamber experiments. We conclude from this study that the dependence under investigation effectively exists, that it is more pronounced for finer-grained films, and that the absolute value of the darkness density does not influence the found results.|
