State-selective single electron capture cross sections are measured by recoil ion momentum spectroscopy technique for He2+ on He at 30keV incident energy. The c
We report a simple and available way of improving the reliability of high power InGaAs 980 nm lasers by cleaning the facets using Ar ion before the protecting f
We introduce the decay rate terms into the density matrix equations of an atom embedded in a photonic band gap (PSG)reservoir successfully.By utilizing the mast
A focused gallium ion (Ga+) beam is used to fabricate micro/submicron spacing gratings on the surface of porous NiTi shape memory alloy (SMA). The crossing type
