Negative muons are negatively charged particles with 206 times the mass of an electron. The chemical properties of atoms and molecules containing these particles were rarely investigated in the last century. However, In recent years a couple of papers have presented measurements of reaction rates for the collisional process He(μ) + H2 → He(μ)H + H, increasing the interest on the chemistry of these exotic systems.
We are studying from a theoretical perspective based on the APMO method the chemical properties of muonic atoms and molecules.
