Determination of chromium on metal surfaces by prompt proton spectrometry
- 22 Downloads
Surface concentrations of chromium were determined non-destructively on copper and nickel substrates by prompt proton spectrometry during irradiation with 3.5 MeV deuterons. Ground state protons from52Cr were used as a measure of the chromium content. The analysis required 5 to 30 min. The relative precision obtained was ±1.8% on copper and ±2.4% on nickel substrates, respectively.
