ANALNRA - CHARGED-PARTICLE NUCLEAR-REACTION ANALYSIS SOFTWARE FOR THE IBM PC

Nuclear reaction analysis (NRA) is a powerful ion beam technique which can only be fully harnessed with suitable analysis software. ANALNRA is a NRA analysis package written for situations when the incident and exiting ions are isotopes of hydrogen and helium. This includes (p, alpha), (d, p), (d, alpha), (He-3, p) and (He-3, alpha) reactions that are used for analysis of many light elements including C, O, F and Al. The package optimises a suitably parameterized distribution of up to five isotopes using nonlinear least squares fitting. The package is written for the IBM PC in Turbo C and uses EGA and VGA graphical interfaces to overlay initial guess and final fits to the raw spectral data.
