Prezhdo, K´alm´an Varga; 2013; Instability of tripositronium; PHYSICAL REVIEW Ahttp://nur.nu.edu.kz/handle/123456789/1089The stability of tripositronium, a system consisting of three electrons and three positrons, has been investigated systematically by varying the repulsion strength between like-charged particles. The possibility of the existence of a Ps3 bound state that is stable against dissociation appears utterly unlikely based on the results of variational calculations employing all-particle explicitly correlated Gaussian basis functionsenAttribution-NonCommercial-ShareAlike 3.0 United StatesResearch Subject Categories::NATURAL SCIENCES::PhysicstripositroniumArticle
