Experimental determination of the nuclear magnetic octupole moment of Ba ion
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We perform precision measurements on the 5D manifold hyperfine intervals of a single trapped ion, Ba. RF spectroscopy is used to measure the hyperfine intervals…
Sub-Doppler Cavity Cooling Beyond The Lamb-Dicke Limit
Boon Leng Chuah, Nicholas C. Lewty, Radu Cazan +1
We investigate the dynamics of cavity cooling of a single ion beyond the Lamb-Dicke regime and demonstrate a cooling limit of approximately 50% of the Doppler temperature using a h…
Minimization of Ion Micromotion in a Linear Paul Trap with a High Finesse Cavity
Boon Leng Chuah, Nicholas C. Lewty, Radu Cazan +1
We demonstrate minimization of ion micromotion in a linear Paul trap with the use of a high finesse cavity. The excess ion micromotion projected along the optical cavity axis or al…
Spectroscopy on a single trapped 137Ba+ ion for nuclear magnetic octupole moment determination
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We present precision measurements of the hyperfine intervals in the 5D3/2 manifold of a single trapped Barium ion, 137 Ba+ . Measurements of the hyperfine intervals are made betwee…
Secondary vortices in swirling flow
Radu Cazan, Cyrus K. Aidun
Twisted tapes are used to induce swirling flow and improve mixing. The flow induced by a 180 degree twisted tape with length (pitch) 60 mm and diameter 25.4 mm in a circular pipe w…
Nuclear Charge Radii of Be-7,9,10 and the one-neutron halo nucleus Be-11
W. Nörtershäuser, D. Tiedemann, M. Žáková +15
Nuclear charge radii of Be have been determined by high-precision laser spectroscopy. On-line measurements were performed with collinear laser spectroscopy in the $2s…
