Frank Henry Read FRS FInstP (born 6 October 1934) is a British physicist.
He made advances in the study of threshold effects in electron collisions, and of post-collision interactions in the near-threshold excitation of resonance states.
His studies of the influence of molecular rotation and vibration on the angular distribution of scattered electrons enabled him to deduce the electronic configurations of short-lived molecular negative ion states.
He also used the technique of delayed coincidences between electrons and photons for the precision measurements of lifetimes for atomic and molecular states.
[2] In 2000, he was awarded the Holweck Prize for his work on atomic and molecular physics.
