Nonlinear Compton scattering requires an electron to absorb multiple laser photons while emitting a single high-energy gamma-ray photon. To observe this phenomenon, researchers approached the ...

A recent Compton-scattering experiment, however, strongly supports a partially covalent picture of the hydrogen bond.

See Srivastava et al. Artistic impression of a nonlinear Compton scattering experiment in which an electron bunch (blue) is accelerated by a laser wakefield to multi-gigaelectron volt energy and ...
