Generations of non-relativistic and relativistic average M shell fluorescence yield (ϖM) (computer code AMSFYLD)

- Generation of average M fluorescence yield values.
- Interpolation of non-relativistic and relativistic data in 60-90 and 70-90 Z-ranges.
- Agreement between generated and actual values supported the adopted procedure.
- Code AMSFYLD gives both data values on terminal/file on entering Z with keyboard/file.
- Work is extension of our earlier work on sub-shell fluorescence and CK yield data.

Average M shell fluorescence yield (ϖM) have been calculated from non-relativistic data of McGuire (Phys Rev A 1972;5:1043-47) in the region Z=60-90 and relativistic data of Chen, Crasemann and Mark (Phys Rev A 1980;21:449-53) and (Phys Rev A 1983;27:2989-94) in the region Z=70-90 on M sub-shell fluorescence yield (ωMi, i=1-5) and Coster-Kronig yield (fMij, i=1-4, j=2-5) procured from our earlier work (a computer software code MFCKYLD) using Scofield׳s data (Lawrence Livermore Laboratory Report UCRL 51326; 1973) on M sub-shell photo-ionization cross-sections. Subsequently, a computer software code AMSFYLD was developed to generate the yield values on computer terminal or in file for both non-relativistic and relativistic data just by entering the atomic number Z of the element through keyboard or file. The values were compared with available theoretical and experimental values in the literature. The agreement between the present data and the other supports the present values.
