Silicon, gallium arsenide and stainless steel samples were implanted w
ith 150 keV C-13 ions at room and liquid-nitrogen temperatures. The de
pth distributions were analyzed by making use of the narrow C-13(p, ga
mma)-resonance at 1.75 MeV. The experimentally determined moments of t
he depth distributions for gallium arsenide and stainless steel are in
reasonable agreement with theoretical predictions. In the case of sil
icon the agreement is less satisfactory, especially as far as the thir
d and fourth moments are concerned. The experimental results indicate
a symmetrical implantation profile in silicon, whilst from theoretical
calculations a strongly skewed distribution is expected.
