Hydrogen in FeTi thin films by ERDA with Ag-107 ions

Hydrogen content in hydride at various depths is very important. In the pre sent work hydrogen content in hydrogenated FeTi thin films has been investi gated by ERDA (Elastic Recoil Detection Analysis) using 160 MeV, Ag-107 ion s. ERDA investigations have shown that FeTi thin films without exposing hyd rogen have about 59 atm% of hydrogen content and after hydrogenation these films acquire 5-10 atm% of additional hydrogen. It was observed that the hy drogenation of irradiated films did not increase the hydrogen concentration further. It implies than a beam did not cause track formation in the sampl e at this energy.
