FORMULAE FOR THE ABSORPTION PATHS OF X-RAY PHOTONS IN THE PARTICLE OF SOME REGULAR SHAPES

Ⅰ. INTRODUCTION Recently, a considerable progress has been made on the Monte Carlo simulation for X-ray quantitative mieroanalysis of particles with no correction for absorption. However, when the quantitative analysis is performed on the particles of larger sizes with the X-ray photons of low energy, the absorption effects should be
