Calculations of the X-ray emission bands of copper using augmented plane wave Bloch functions

The L and M X-ray emission bands of metallic copper are calculated in the one-electron approximation using augmented plane wave Bloch functions analysed into s, p and d symmetry components. The effect on the calculated intensity distributions of lifetime broadening due to Auger processes is estimated in a simple manner, and appropriately broadened curves are compared with the available experimental data.
