Electron, positron, and heavy-particle collisions with molecules. This project aims to develop a computational approach to collisions involving molecular targets with electrons, positrons and heavy particles. Recently, the approach to atomic collisions, the Convergent Close Coupling (CCC) method, has been extended and verified for positron, electron, and heavy particle collisions with the simplest molecular systems (molecular hydrogen and its ion). This project now aims to extend the CCC method ....Electron, positron, and heavy-particle collisions with molecules. This project aims to develop a computational approach to collisions involving molecular targets with electrons, positrons and heavy particles. Recently, the approach to atomic collisions, the Convergent Close Coupling (CCC) method, has been extended and verified for positron, electron, and heavy particle collisions with the simplest molecular systems (molecular hydrogen and its ion). This project now aims to extend the CCC method to study collisions with more complex molecules. Expected benefits include more accurate data for diagnostic tools such as Positron Emission Tomography, and potential advances in particle-based cancer therapy.Read moreRead less
Antihydrogen formation. This project aims to advance fundamental understanding of collisions involving antimatter. The dominance of matter over antimatter in the Universe is one of the most intriguing questions of today’s science. Researchers at the European Organisation for Nuclear Research (CERN) are addressing this question by creating antihydrogen and studying its properties, including the gravitational behaviour. By trapping and cooling antihydrogen positive ions, ultra-cold antihydrogen at ....Antihydrogen formation. This project aims to advance fundamental understanding of collisions involving antimatter. The dominance of matter over antimatter in the Universe is one of the most intriguing questions of today’s science. Researchers at the European Organisation for Nuclear Research (CERN) are addressing this question by creating antihydrogen and studying its properties, including the gravitational behaviour. By trapping and cooling antihydrogen positive ions, ultra-cold antihydrogen atoms can be created and used in free fall experiments at CERN. The convergent close-coupling method and threshold theory will be used to provide the necessary theoretical guidance for the experimental antihydrogen positive ion formation via low-energy positronium-antiproton and positronium-antihydrogen collisions.Read moreRead less
