Possible outcomes of a neutron interaction with a boron-10 atom of the layer: (a) α-particle is emitted in the direction of the proportional gas, with energy loss in the boron-10 layer; (b) ⁷Li is emitted in the proportional gas, with energy loss in the boron-10 layer. Right: Pulse-height distribution recorded with a boron-10 linned proportional counter, adapted from¹⁰. Interactions of type (a) produce events with energies up to the α-particle threshold. Super-imposed on these are the type (b) events, with maximum energy corresponding to the ⁷Li energy.
