3. NATURE OF PHYSICAL PROBLEM SOLVED

This code analyzes alpha spectra  measured by solid-state detectors to extract information on the peak intensities and energies.
[ top ]
4. METHOD OF SOLUTION

The code performs peak search by the photopeak method, generates the line-shape function consisting of the first and/or second order and decomposes the peak compound by the function-minimizing fitting method using the line-shape function.
[ top ]
5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Up to 4100 channels are accepted. The total number of peaks should not exceed 50 and the maximum  multiplicity is 19.
[ top ]
6. TYPICAL RUNNING TIME

The running time is less than 10 seconds for the case  of a spectrum with medium complexity.
