Test of Lorentz invariance in decay of polarized
A. Sytema, J. E. van den Berg, O. Böll +17
We search for a dependence of the lifetime of nuclei on the nuclear spin direction. Such a directional dependence would be evidence for Lorentz-invariance violatio…
A gas cell for stopping, storing and polarizing radioactive particles
A. Sytema, J. E. van den Berg, O. Böll +14
A radioactive beam of 20Na is stopped in a gas cell filled with Ne gas. The stopped particles are polarized by optical pumping. The degree of polarization that can be achieved is s…
Measurement of the branching ratio for beta-delayed alpha decay of 16N
J. Refsgaard, O. S. Kirsebom, E. A. Dijck +10
While the 12C(a,g)16O reaction plays a central role in nuclear astrophysics, the cross section at energies relevant to hydrostatic helium burning is too small to be directly measur…
Determination of transition frequencies in a single Ba ion
E. A. Dijck, M. Nuñez Portela, A. T. Grier +4
Transition frequencies between low-lying energy levels in a single trapped Ba ion have been measured with laser spectroscopy referenced to an optical frequency comb.…
