Penning trap mass spectrometry for nuclear structure studies,tigation of nuclear structure. Precise nuclear masses with less than 0.1 ppm relative mass uncertainty allow stringent tests of mass models and formulae that are used to predict mass values of nuclides far from the valley of stability. Furthermore, an investigation of nuclear structure effects likeGrating 发表于 2025-3-25 22:33:40

Development of a RILIS ionisation scheme for gold at ISOLDE, CERN,ffuse from the target. The RILIS process of laser step-wise resonance ionisation of atoms in a hot metal cavity provides a highly element selective stage in the preparation of the radioactive ion beam. As a result, the ISOLDE mass separators can provide beams of a chosen isotope with greatly reducedGORGE 发表于 2025-3-26 07:16:16
The ALTO project at IPN-Orsay,rsay offers a unique opportunity to compare the performance of a laser ion guide under different regimes. The ALTO accelerator has delivered its first electron beam at the end of 2005 and a design for a gas-cell prototype is being studied.羽饰 发表于 2025-3-26 09:06:02
Upgrade to the IGISOL laser ion source towards spectroscopy on Tc, upgrade has led to a factor of two improvement in the output power, and has been directly employed in the first off-line laser ionisation tests on the long-lived refractory isotope .Tc. In the future further studies will be done to determine the efficiency of this ionisation scheme and to employ itPainstaking 发表于 2025-3-26 13:49:30

Nuclei near the closed shells ,=20 and ,=28,as one goes away from the ß-stability line are discussed. The location of the neutron drip line and questions about the stability of nuclides with .≥8 are considered in connection with the weakening or even vanishing of the shell effects at the magic numbers 20 and 28, and the discovery of the new nextinct 发表于 2025-3-27 07:04:21

The magnetic moment of .Mg was derived from its hyperfine structure detected in UV fluorescent light, whereas the nuclear magnetic resonance observed in β-decay asymmetry from a polarised ensemble of nuclei gave the mag
