O107300100027 SAMPLE The 0.1-mm thick Ta target was oriented with its O107300100028 normal antiparallel to the beam direction. O107300100029 The deuterated Ta target was produced in the following O107300100030 way. A fresh Ta foil was bombarded with 10-KeV O107300100031 deuterons, whereby the deuterons were scanned over the O107300100032 target area leading to a 20% current reduction comparedO107300100033 to the unscanned case, a stoichiometry Ta(X)D has been O107300100034 produced near the surface of the Ta sheet. The O107300100035 deuterated Ta sheet should thus represent an infinitelyO107300100036 thick target for the incident deuterons. The deuteron O107300100037 distribution was uniform within 10% from the surface ofO107300100038 the Ta sheet down to depths beyond the range of the O107300100039 implanted deuterons, apparently due to a rapid O107300100040 diffusion of D and Ta.
