Importance of Considering Helium Excited States in He+ Scattering by An Aluminum Surface

The He+/Al system is a very interesting projectile-surface combination which was thought initially as an example of a pure Auger neutralization mechanism. Then, because of the measured reionization explained by the antibonding interaction of the projectile state with the core … Continue reading

Shift and Broadening of Resonance Lines of Antiprotonic Helium Atoms in Solid Helium

We have estimated the shift and broadening of the resonance lines in the spectrum of antiprotonic helium atoms $\bar{p}\mathrm{He}^{+}$ implanted in solid helium $^4$He. The application of the response function for crystalline helium has enabled determination of the contributions from … Continue reading
