Lithography can be performed with beams of neutral atoms in metastable excited states to pattern self-assembled monolayers (SAMs) of alkanethiolates on gold. An estimated exposure of a SAM of dodecanethiolate (DDT) to 15 to 20 metastable argon atoms per DDT molecule damaged the SAM sufficiently to allow penetration of an aqueous solution of ferricyanide to(More)
Atomic spectroscopy results from the electron beam ion trap at the National Institute of Standards and Technology have generally agreed with the predictions of theory extremely well. An interesting exception is our recent result on the helium isoelectronic sequence at Z = 22, which agrees instead with a meta-analysis of all prior measurements above Z = 15,(More)

The behavior of exotic highly charged ions can be studied spectroscopically in an Electron Beam Ion Trap (EBIT). The EBIT produces customized, well-characterized, homogeneous plasmas for a wide variety of precision measurements. It is uniquely capable of simulating astrophysical plasma conditions to systematically examine how the atomic structure and(More)
