REEARCH PROGRESS OF POSITRON-BASED ANTIMATTER

Shaojie Wang

Positron,an antiparticle of electron,is much more easily obtained than other's antipartices,such as antiproton,antihydrogen,thus electron-positron system is the most suitable way for studying the combination of common matter and antimatter.In this article,we describe the history,current state and future prospect of antimatter(positron) research in combination with first laboratory synthesis of matter-antimatter molecule;and emphasizes on the experimental techniques based on positron trapping,confinement and accumulation,and the production of molecular positronium.Positron,an antiparticle of electron,is much more easily obtained than other's antipartices,such as antiproton,antihydrogen,thus electron-positron system is the most suitable way for studying the combination of common matter and antimatter.In this article,we describe the history,current state and future prospect of antimatter(positron) research in combination with first laboratory synthesis of matter-antimatter molecule;and emphasizes on the experimental techniques based on positron trapping,confinement and accumulation,and the production of molecular positronium.

Simulation of the formation of antihydrogen via magnetobound positronium

F. F. Aguirre, Carlos A. Ordonez

Antihydrogen formation involving magnetobound positronium is simulated by computing classical trajectories. Simulated collisions between electrons and positrons generate magnetobound positronium, which consists of electron–positron pairs that are not energetically bound but that have spatially correlated trajectories within a magnetic field. Simulations show that antihydrogen can form if such electron–positron pairs pass near antiprotons. In addition, the possibility of forming antihydrogen atomic ions or antihydrogen molecular ions via magnetobound positronium or magnetobound antihydrogen is discussed.Antihydrogen formation involving magnetobound positronium is simulated by computing classical trajectories.
