properties of several yet-to-be-discovered elements. 28. What is the periodic law? When the elements are arranged by increasing atomic number, there is a periodic repetition of their chemical and physical properties. 29. Describe the general characteristics of metals. Metals are generally dense, solid, shiny, ductile,

Physics of PET - University of Washington

Currently, BGO and LYSO is favored by GE, LSO by Siemens, and LYSO by Philips. Recently developed time-of-flight PET scanners (TOF-PET) use the scintillator LYSO, which has properties that are very similar to LSO. Table 1. Scintillators used in PET Scanners.

Chapter 8 Hyper-Pure Germanium Detector

In both Si and Ge, the material with highest available purity tends to be p-type, which requires addition of donor atoms for compensation. The alkali metals like Li, Na tend to form interstitial donors in Si and Ge. When one of these donor materials (practically Li) is introduced into Si or Ge, the donor atoms are easily ionized
