Abstract

Ultrahigh vacuum equipment has been installed for the analysis of hydrogen by the hydrogen-1(nitrogen-15, alpha gamma)carbon-12 resonant nuclear reaction. The main characteristics are the possibility of cooling a large sample holder rapidly with liquid nitrogen and the measurement of the incident beam dose with a spinning wire system.

The details of this set-up are presented and the precision in the measurement of the integrated currents based on the backscattering of the ions on the spinning wire discussed. The presented applications concern observations of the Doppler broadening of the resonance for hydrogen adsorbed on pure silicon crystals. Buffered hydrogen fluoride solutions have been used in order to prepare silicon-100 and silicon-111 surfaces. .
