A measurement of the Panofsky ratio in helium-3
The Panofsky ratio in ³He, P₃= ω(π⁻³He→³Hπ°)/ω(π⁻³He→³Hγ) , has been measured experimentally for absorption of negative piohs at rest. A 30 MeV π⁻ beam was degraded and stopped in a 1.9 cm thick liquid ³He target. The high-energy photons, from the inflight π°→γγ decay and the radiative capture chann...
