B. Rajchel, BSCAT - CODE FOR SIMULATION AND FOR ANALYSIS OF THE RBS NRA SPECTRA/, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 113(1-4), 1996, pp. 300-302
A beam of charged particles as a tool for non-destructive analysis of
the structure and elemental composition of thin-surface layers is freq
uently used in material investigations. Nuclear methods such as RBS or
NRA techniques have a good depth resolution and sufficient mass sensi
tivity. Many computer programs exist, like the RUMP [see L.R. Doolitle
, Nucl. Instr. and Meth. B 9 (1985) 344] or DVBS [see V. Bohac and D.M
. Shirokov, Nucl. Instr. and Meth. B 84 (1994) 497] codes, for simulat
ion and for analysis of experimental results collected in measurements
with beams of charged particles. A new computer code, called BSCAT (B
ackSCATtering), was created at the institute of Nuclear Physics to ana
lyze experimental spectra and to simulate new experiments. The BSCAT c
ode, written in FORTRAN-77 and partially in C, can work on IBM persona
l computers or on larger computers such as CONVEX machines. As input f
or the program both Rutherford and non-Rutherford cross sections can h
e used and the stopping power function can be calculated by the Ziegle
r or the Montenegro formula. The program was used in the analysis of c
omplex spectra of backscattered particles. Among other applications th
e BSCAT code was used for analysis of the spectrum of 2100 keV protons
bombarding a thin carbon foil created by the IBAD technique on the su
rface of a Si[111] single crystal [C-12(p, p)C-12 and Si-28(p, p)Si-28
resonance].
