Applications of conversion electron Mössbauer spectrometry (CEMS)

Magnetic texture determination by conversion electron Mössbauer spectroscopy with circularly polarized beam

“…Magnetic field distribution, produced by system of permanent magnets, acting on the sample (represented as a circle). Table 1 The average square of the cosine h(cm) 2 i, the average cosine hcmi values determined from CEMS measurements of a-57 Fe foil and the average square of the cosine h(cb) 2 …”

“…In contrast, this kind of problem does not exist when backscattered electrons, emitted after nuclear resonant absorption, are observed. Moreover, because of the high signal to noise ratio, conversion electron Mössbauer spectroscopy (CEMS) [1,2] can also be used for studies of relatively thin samples.…”

Automation in M�ssbauer spectroscopy data analysis

“…The best resolution counting in energy may be achieved by semiconductor detectors at the expense of counting rate, while a lower resolution can be obtained by proportional detectors but which give a higher counting rate. Figure 3 depicts the inner conversion process after the Mö ssbauer effect of 57 Fe nuclei [9]. Calibration of the measuring apparatus (channel number for each velocity unit and determination of 0 mm/s-central spectrum point) is performed with the aid of absorbers with very well known hyperfine parameters.…”

Observation of nuclear gamma resonance with superconducting tunnel junction detectors

“…12 Various applications of CEMS with different detectors but without LTDs were considered in the review. 13 We proposed some possible schemes of the STJ Mössbauer resonance detectors in Ref. 14.…”
