Through measuring the energy distributions of H+ and D+ fragments for HD+2 beam incident on carbon foils at energy 1.4977 MeV, a very large ‘wake effect’ has been found and the structure of HD+2 has been determined....Through measuring the energy distributions of H+ and D+ fragments for HD+2 beam incident on carbon foils at energy 1.4977 MeV, a very large ‘wake effect’ has been found and the structure of HD+2 has been determined. The result shows an asymmetry configuration for HD+2. It agrees with other experimental results and support several assumptions.展开更多
Thin calcium phosphate catings on titanium alloy substrates were prepared by Ar^+ ion beam assisted deposition(IBAD) from hydroxyl-poly-calcium sodium phosphate(HPPA) target.The coatings were analyzed by XRD,FTIR,XPS,...Thin calcium phosphate catings on titanium alloy substrates were prepared by Ar^+ ion beam assisted deposition(IBAD) from hydroxyl-poly-calcium sodium phosphate(HPPA) target.The coatings were analyzed by XRD,FTIR,XPS,These analyses revealed that the as-deposited films were amorphous or no apparent crystallinity.No distinct absorption band of the hydroxyl group was observed in FTIR spectra of the coatings but new absorption bands were presented for CO3^-2,The calcium to phosphorous ratio of these catings in different IBAD conditions varied from 0.46 to 3.36.展开更多
