A Pascal program for the least-squares evaluation of standard RBS spectra
Description
Abstract A computer program for least-squares fitting of energy spectra obtained in common Rutherford backscattering (RBS) analyses is described. The samples analyzed by RBS technique are considered to be made up of a finite number of layers, each with uniform composition. The RBS spectra are treated as a combination of variable number of three different basic figures (strip, bulge and Gaussian) which are represented by ad-hoc chosen analytical expressions. The initial parameter estimates are inserted... Title of program: RBSFIT Catalogue Id: ACJR_v1_0 Nature of problem The program serves for the determination of basic parameters, e.g. positions, amplitudes and areas of specific components appearing in the energy spectra of elastically scattered particles. Versions of this program held in the CPC repository in Mendeley Data ACJR_v1_0; RBSFIT; 10.1016/0010-4655(92)90156-S This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
