The values of (μ<sub>msub>) i.e. mass attenuation coefficients are calculated.
We report the values of total atomic cross-sections (σ<sub>t, asub>).
Measurement of electronic cross-sections (σ<sub>t.elsub>) of nonlinear optical materials.
Comparison of all (μ<sub>msub>), (σ<sub>t, asub>), (σ<sub>tsub>,<sub>elsub>) values with XCOM program.
