Optically Polarized He
T. R. Gentile, P. J. Nacher, B. Saam +1
This article reviews the physics and technology of producing large quantities of highly spin-polarized, or hyperpolarized, He nuclei using spin-exchange (SEOP) and metastabilit…
Measurement of the charged pion mass using a low-density target of light atoms
M Trassinelli, D. F. Anagnostopoulos, G Borchert +10
We present a new evaluation of the negatively charged pion mass based on the simultaneous spec-troscopy of pionic nitrogen and muonic oxygen transitions using a gaseous target comp…
High-precision spectroscopy of the HD+ molecule at the 1-p.p.b. level
J. Biesheuvel, J. -Ph. Karr, L. Hilico +3
Recently we reported a high precision optical frequency measurement of the (v,L):(0,2)->(8,3) vibrational overtone transition in trapped deuterated molecular hydrogen (HD+) ions at…
Hydrogen molecular ions for improved determination of fundamental constants
J. -Ph Karr, L Hilico, Jeroen Koelemeij +1
The possible use of high-resolution rovibrational spectroscopy of the hydrogen molecular ions H + 2 and HD + for an independent determination of several fundamental constants is an…
Measurement of the charged pion mass using X-ray spectroscopy of exotic atoms
M Trassinelli, D. F. Anagnostopoulos, G. Borchert +10
The transitions in pionic nitrogen and muonic oxygen were measured simultaneously by using a gaseous nitrogen-oxygen mixture at 1.4\,bar. Due to the precise knowledge of th…
Probing QED and fundamental constants through laser spectroscopy of vibrational transitions in HD+
J. Biesheuvel, J. -Ph. Karr, L. Hilico +3
The simplest molecules in nature, molecular hydrogen ions in the form of H2+ and HD+, provide an important benchmark system for tests of quantum electrodynamics in complex forms of…
