Welcome to the Laboratory of Positron and Positronium Physics. Sometimes you are only able to find a solution when looking from a different angle. The use of positron ... AAPM is a scientific, educational, and professional nonprofit organization devoted to the discipline of physics in medicine. Abstract. In our previous consideration, the so-called ambiguities of quantum field theory can be removed by the certain general conditions of integrals. T.
