| lorentz ionisation | <physics> Ionisation of neutral atoms (taken generally at a highly-excited state) obtained by launching them at high velocity across a strong magnetic field. The neutral atoms feel an electric field proportional to their perpendicular velocity times the magnetic field strength, and if this electric field is strong enough ionisation can occur.
