Coherent control mechanisms of Penning and associative ionization in cold He${}^{\ast }(2^3\text{S})$-He${}^{\ast }(2^3\text{S})$ reactive scattering

Juan J. Omiste, Timur V. Tscherbul, Paul Brumer

We explore coherent control of Penning and associative ionization in cold collisions of metastable He${}^{\ast }(2^3\text{S})$ atoms via the quantum interference between different states…
