Dipole and quadrupole moments of Cu73–78 as a test of the robustness of the Z=28 shell closure near Ni78

R. P. de Groote, J. Billowes, Cory L Binnersley, M. L. Bissell et autres

Nuclear spins and precise values of the magnetic dipole and electric quadrupole moments of the ground states of neutron-rich $^{73\text{--}78}\mathrm{Cu}$ isotopes were measured using the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at the CERN On-Line Isotope Mass Separator (ISOLDE) facility. The nuclear …

Collinear laser spectroscopy with the COLLAPS setup

M. L. Bissell, W. Nörtershäuser, I. Budinčević, S. Rothe et autres

At the beginning of long shutdown 1, three collinear laser spectroscopy experiments using the COLLAPS setup remained open.IS519 (Zn) has yet to be scheduled, IS508 (Mn) was able to take 11 of the 18 shifts approved and IS529 (Ca) successfully completed all …

Antihydrogen physics: gravitation and spectroscopy in AEgISThis paper was presented at the International Conference on Precision Physics of Simple Atomic Systems, held at École de Physique, les Houches, France, 30 May – 4 June, 2010.

R. Ferragut, А. С. Белов, G. Bonomi, I. Boscolo et autres

AEgIS (Antimatter experiment: gravity, interferometry, spectroscopy) is an experiment approved by CERN with the goal of studying antihydrogen physics. In AEgIS, antihydrogen will be produced by charge exchange reactions of cold antiprotons with positronium atoms excited in a Rydberg state (n > …

Measuring the fall of antihydrogen: the AEgIS experiment at CERN

M. Doser, Y. Allkofer, C. Amsler, А. С. Белов et autres

Considerable efforts have been made and are still being made to verify the validity of the principle of the equivalence of gravitational and inertial mass, one of the cornerstones of the classical theory of general relativity. Specific attempts at quantummechanical formulations of …

Nuclear ground-state spin and magnetic moment of 21Mg

Jörg Krämer, K. Blaum, M. De Rydt, K. T. Flanagan et autres

We present the results of combined laser spectroscopy and nuclear magnetic resonance studies of 21Mg. The nuclear ground-state spin was measured to be I=5/2 with a magnetic moment of μ=−0.983(7)μN. The isoscalar magnetic moment of the mirror pair (F21,Mg21) is evaluated and …

Formation Of A Cold Antihydrogen Beam in AEGIS For Gravity Measurements

G. Testera, А. С. Белов, G. Bonomi, I. Boscolo et autres

The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the apparatus and realistic hypothesis about the antihydrogen initial conditions are shown. The resulting velocity distribution …

Spin and Magnetic Moment of Mg33 : Evidence for a Negative-Parity Intruder Ground State

D. T. Yordanov, K. Blaum, M. De Rydt, K. T. Flanagan et autres

We report on the first determination of the nuclear ground-state spin of 33Mg, I=3/2, and its magnetic moment, mu= -0.7456(5) mu(N), by combining laser spectroscopy with nuclear magnetic resonance techniques. These values are inconsistent with an earlier suggested 1 particle-1 hole configuration …

Magnetic Resonance in Radiating or Absorbing Atoms: The MIT Connection of Jean Brossel

H. H. Stroke

The motivation of Francis Bitter to combine optical excitation and radiofrequencies for a spectroscopy with sensitivity adequate for work with radioactive atoms, and the implementation with Jean Brossel, are highlighted. The recounting provides background for the USA period of Brossel's early work …
