A feasible and fruitful way to study the spectroscopy of hypernuclei has been demonstrated by two experiments that applied counter techniques to measure hypernuclear reactions induced by mesons in flight. Such studies have been made possible in recent years by the development of intense, low‐momentum beams. They were further stimulated by the suggestions of theorists that production of hypernuclei by mesons in flight might favor the formation of states in which a nucleon of the parent nucleus is replaced by a lambda hyperon without otherwise changing the wave functions. Comparison of such a hypernuclear state with the corresponding nuclear state could yield useful information about the lambda–nucleon interaction.
