Covalent Bonding in Positron Dihalides: A New Stable Ma�er-Antima�er Binding
Antimatter
Matter
Theoretically, atoms are combined into molecules through covalent bonds in which positrons are
shared instead of electrons
H H
Positrons (e+) are electron (e-) analogues with a positive charge
Can positronic bonding occur beyond the simple e+[H-H-] molecules?

Formation of energetically stable positronic molecules are possible far beyond the previously addressed e+[H-H-] molecule
