Abstract :
A computer program has been developed in TURBO C++ to obtain theoretical X-ray satellite spectrum. Using the available theories for the origin of the X-ray satellite spectral lines, we calculate the energies and intensities of the different possible electronic transitions which give rise to the satellites. The energies and intensities of the transitions are fed in the developed computer program. The energy is taken as X and the intensity as Y. The position of each line is taken to be the energy of transition on X-axis and the height of each line is taken to be equal to the relative intensity on Y-axis. Each spectral line corresponding to a transition is taken as a Gaussian line. The data for each Gaussian line is computed by the program. The data for composite spectrum of all the electronic transitions, i.e., for the envelope of all the Gaussian curves is computed by the program. The data obtained as the output of the program is plotted as a graph, using software Origin. The graph obtained is the theoretical X-ray satellite spectrum. This theoretical spectrum is compared with the available experimental results and the origin of the satellites is explained. In the present paper, we are reporting the algorithm, the developed computer program and the outputs obtained using the program. The program is versatile and can be used to obtain any theoretical spectrum when the energies and intensities of the transitions giving rise to the spectrum are known.
