Exposing pressurized crystals to GeV heavy ions reveals unexpected structural changes. Irradiated at ambient conditions, natural zirconia (ZrO2) transforms from the monoclinic structure to its tetragonal (high-temperature) phase. For this process the required fluence must exceed 5×10 12 ions/cm 2 for Pb and U, and become even significantly higher for(More)
We present the first complete infrared spectrum of a molecular cloud core covering the wavelength region from 2.4 up to 200 µm together with a map at 1.3 mm wavelength and near-infrared (NIR) images. The core is located in the northern part of M 17 and shows strong evidence for ongoing star formation. These data are the first step towards a complete(More)
