Hyperfine structure and isotope shifts of the transition in atomic zinc
David Röser, J. Eduardo Padilla-Castillo, Ben Ohayon +5
We report absolute frequency, isotope shift, radiative lifetime and hyperfine structure measurements of the (213.8 nm) transition in Zn I using a cryog…
All-optical Differential Radii in Zinc
B. K. Sahoo, B. Ohayon
We conduct high-accuracy calculations of isotope shift (IS) factors of the states involving the and lines in Zn II. Together with a global fit to the available optical…
High-resolution isotope-shift spectroscopy of Cd I
Simon Hofsäss, J. Eduardo Padilla-Castillo, Sid C. Wright +6
We present absolute frequency measurements of the (nm) and (nm) transitions…
Isotope Shifts in Cadmium as a Sensitive Probe for Physics Beyond the Standard Model
B. Ohayon, S. Hofsäss, J. E. Padilla-Castillo +5
Isotope shifts (ISs) in atomic energy levels are sensitive probes of nuclear structure and new physics beyond the Standard Model. We present an analysis of the ISs of the cadmium a…
Measurement of the == transition in Muonium
G. Janka, B. Ohayon, I. Cortinovis +9
Muons are puzzling physicists since their discovery when they were first thought to be the meson predicted by Yukawa to mediate the strong force. The recent results at Fermilab on…
Precision measurement of the Lamb shift in Muonium
B. Ohayon, G. Janka, I. Cortinovis +10
We report a new measurement of the Lamb shift in Muonium using microwave spectroscopy. Our result of MHz comprises an order of…
Nuclear charge radii of Na isotopes: A tale of two theories
B. Ohayon, R. F. Garcia Ruiz, Z. H. Sun +3
The accuracy of atomic theory calculations limits the extraction of nuclear charge radii from isotope shift measurements of odd-proton nuclei. For Na isotopes, though precise spect…
Isotope shifts in Ne -- Precision measurements and global analysis in the framework of intermediate coupling
B. Ohayon, H. Rahangdale, A. J. Geddes +2
We report new precision measurements of the Ne--Ne isotope shift for several transitions, as well as state-of-the-art, \textit{ab initio} field-shift calculations. Ou…
Imaging recoil ions from optical collisions between ultracold, metastable neon isotopes
B. Ohayon, H. Rahangdale, J. Chocron +3
We present an experimental scheme which combines the well established method of velocity-mapimaging, with a cold trapped metastable neon target. The device is used for obtaining th…
Characterization of a metastable neon beam extracted from a commercial RF ion source
B. Ohayon, E. Wåhlin, G. Ron
We have used a commercial RF ion-source to extract a beam of metastable neon atoms. The source was easily incorporated into our existing system and was operative within a day of in…
New Approaches in designing a Zeeman-Slower
Ben Ohayon, Guy Ron
We present two new approaches for the design of a Zeeman-Slower, which rely on optimal compliance with the adiabatic following condition and are applicable to a wide variety of sys…
