Negative Ion Formation in Complex Heavy Systems – Dr Alfred Msezane, Clark Atlanta University
When an electron is absorbed by a heavy atom or molecule, a heavy, negatively-charged ion is formed. These negative ions can be used for a wide array of useful applications, from organic solar cells to water purification. However, the electron absorption process for heavy particles is a complex many-body process, making it difficult for physicists to understand how the ions form. Dr Alfred Msezane at Clark Atlanta University has developed a robust mathematical theory to gain a fundamental understanding of negative ion formation in such heavy systems for the first time.
