Ph. Barker, ALIGNING A GE DETECTOR USING THE F-19(P,ALPHA-GAMMA) REACTION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 345(3), 1994, pp. 445-448
Considerations of symmetry and energy of the Doppler-broadened full en
ergy peak of the 7.1 MeV gamma ray emitted following the F-19(p,alpha)
O-16 reaction have been used to set a Ge detector to look at a target
at 90-degrees to the proton beam axis.
