【 摘 要 】

A continuous wave (CW) Ar ion laser producing photons at 244 nm (doubled from the fundamental wavelength at 488nm) was used to ionize neutrals sputtered from representative lanthanide (neodymium oxide, Nd₂O₃) and actinide (uranium oxide, U₃O₈) containing materials in the modified Cameca ims-4f at PNNL.
