# Neutrons; Lyman alpha photons

## Appears In

                        - New NIST Detector Can 'See' Single Neutrons Over Broad Range

Neutron absorption by 3He yields tens of Lyman alpha photons, which result from the most fundamental energy jump in the hydrogen atom. This schematic illustrates the operation of a prototype Lyman alpha neutron detector (LAND).
