Abstract:

The mass absorption coefficients for X-ray of λ=31.5 Å (NK α ) and λ=67.6 Å (BK α ) have been determined by the use of EPMA and a special composite target.
The composite target was prepared by means of the evaporation of Al, Ca, Cr, Cu, Se, Zr, Ag, Sb, La, Gd, Au or Bi on BN base in vacuum (∼10-5 mmHg).
The mass absorption coefficients of these metals for the NK α line and the BK α line were determined from the experimental results by using the following equation:
