We have measured the depth distribution of P-31 ions implanted at 50 keV to
a fluence of 7 x 10(15)/cm(2) into Ge using two methods: first, the surfac
e-sensitive particle-induced X-ray excitation (PIXE) technique utilizing io
n-induced X-ray emission has been exploited for absolute non-destructive an
alysis; second, secondary ion mass spectrometry has been performed to obtai
n the relative depth distribution for the same target. (C) 1999 Elsevier Sc
