In 2006 the mass measurements at the tandem Penning trap spectrometer ISOLTRAP
investigated short-lived nuclides relevant for superallowed beta decays, nuclear
structure, and nucleosynthesis. After the installation of a new detector [1] and a
temperature stabilization system, which improved respectively the precision and the
accuracy of the experiment, a new excitation scheme has been...

Shape coexistence at low excitation energy in nuclei has continuously shown
much interest on both experimental and theoretical fronts. The region around
the neutron mid-shell (N = 104) and closed proton shell (Z = 82) is of special
interest. For example, in Pb at N = 104, it has been found that the three
lowest lying states have 0+ as spin and parity values, these states have been...

Collinear laser spectroscopy measurements of nuclear moments and mean-square charge
radii at JYFL have benefited from the introduction of an ion beam cooler. The
reduced energy spread of the emerging beam increases the spectral resolution while
the smaller emittance allows a narrower waist of the laser-ion overlap, thus
requiring less laser power. A lower background from the decreased...

Since introduced in nuclear physics, the concept of shell structure and magic numbers
has governed our understanding of nuclear matter in atomic nuclei close to stability.
Experimental research in 30Ne, 31Na and 32Mg, systems with a closed neutron sd shell
(N=20), provided evidence for a ground state deformation in these nuclei. The
observed phenomenon is understood as an inversion of the...

The WITCH experiment aims to study a possible admixture of a scalar or tensor type
interaction in beta decay by determining the beta-neutrino angular correlation from
the shape of the recoil energy spectrum. The experimental set-up couples a double
Penning trap system to form a scattering-free radioactive source and a retardation
spectrometer to probe the recoil ion energy. The intensive...

The evolution of nuclear structure with neutron excess
in the copper isotope chain is currently under investigation by
the COLLAPS collaboration. This experiment uses high-resolution
laser spectroscopy, which unambiguously measures the nuclear spin
and provides model-independent measurements of nuclear moments. It
is therefore an ideal tool to study the nuclear structure. In the
isotopes...
