摘要: Abstract The observed deficit of the solar neutrino flux is now well established. This puzzling problem today's particle physics could be resolved soon. most likely explanation would vacuum oscillation phenomenon, indirectly proving non-zero mass these fleeting particles. Following proposition Raghavan using 176 Yb as a target for low-energy spectroscopy, an intense R&D work has started few years ago to define suitable scintillator incorporating large amount ytterbium. Recently, observation UV scintillation in mixed yttrium/ytterbium aluminium garnets opened field investigation new class scintillating crystals with interesting luminescence properties, very attractive not only but also radiation detection, general. Their properties present some peculiarities that make them by themselves.
