T. Ruskov et al., LOW-TEMPERATURE SYSTEM FOR SIMULTANEOUS COUNTING OF CONVERSION ELECTRONS AND BACKSCATTERED GAMMA-RAYS IN MOSSBAUER-EFFECT EXPERIMENT, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 94(4), 1994, pp. 565-568
A system for simultaneous detection of conversion electrons, emitted a
fter resonant exciting of Fe-57, and resonant backscattered gamma-rays
and X-rays, accompanying the conversion electrons, is described. The
system includes a helium proportional counter, for detection of conver
sion electrons, and a toroidal ''Keisch-type'' proportional counter, c
onnected to the vacuum part of a helium cryostat.
