Small tungsten cluster anions Wn− (n=4–9 and 18–20) are stored in a Penning trap and electronically excited by photoabsorption (Ehν=1.815, 2.33, 3.5, and 4.66 eV). Delayed electron emission is observed on the milliseconds time scale by systema

Muon-spin rotation experiments were carried out on Cd{sub 1{minus}x}Mn{sub x}Te samples with different Mn concentrations x and different annealing treatments (in Cd vapor or in vacuum). The purpose of the experiment was to elucidate the origin of the

Photoelectron spectra of small mass-separated Wn− clusters cooled cooled in a seeding gas are recorded with a low laser flux that ensures single-photon events. The spectra exhibit (i) sharp features due to direct photoemission and (ii) a broad emis

Zero-field muon-spin rotation (ZF-μSR) experiments were performed on hydrogen-doped YBa2Cu4O8. The observation of well defined muon-spin precession frequencies unambiguously demonstrates the presence of local magnetic order. From the magnitude and t

Hydrogen-free amorphous carbon films produced by direct deposition of low energy carbon ions exhibit diamond-like properties such as extreme hardness, large band gap and high index of refraction. Using mass separated ion beam deposition, high purity

We report on delayed electron emission from free tungsten clusters, excited by light from a Q‐switched YAG laser. Using a novel ion extraction lens, electron emission can be analyzed over a time range of 50 ns–5 μs after the laser pulse without

Positive muons injected into solid ${\mathrm{C}}_{70}$ form a vacuumlike muonium (Mu) state with a 25% probability. This state is attributed to muons inside the ${\mathrm{C}}_{70}$ cage (${\mathrm{C}}_{70}$:Mu). In addition, three different types of
