Thermal Helium Desorption Spectrometry (HDS) has been used to study the room temperature nuclea-tion of helium precipitates at point defects inNi(llO), notably HeV defects at depth- 20 nm below the crystal surface. Helium is injected into the crystal by 50 eV He ion-irradiation which causes no atomic displacements. It has been observed that He,V defects with occupation from n = 2 He to n = 4 He bind helium equally strongly,but weaker than for HeV. For n35 He the binding increases rapidly. The observed behaviour is attributed to helium induced trapmutation and agrees qualitatively with results of atomistic calculations in nickel for this case. Helium precipitation at near surface trapping sites is held responsible for the observed increase o...
