A new detection system for backscattering Mössbauer spectroscopy
- 16 Downloads
The construction and characteristics of a new detection system are described in the paper. This new detector consists of five wire planes, two of which are anode planes and three of which are cathode planes. Because two MWPC's with different parameters are adopted, the Mössbauer spectra of the conversion electron, resonance scattering γ-ray, Kx-ray and their coincidence spectrum can be recorded separately. The multiple Mössbauer spectra of the surface layer of several samples is shown.
