The REX-ISOLDE project

1998

Abstract REX-ISOLDE [1] is an experiment at ISOLDE/CERN with a twofold aim: (i) to demonstrate a novel efficient scheme for the acceleration of radioactive ions from the online mass separator ISOLDE to energies around the Coulomb barrier. (ii) to perform first nuclear physics experiments by studying the structure of the neutron-rich (N = 20, N = 28) nuclei by Coulomb excitation and neutron transfer reactions. An overview on the different components of the radioactive beam accelerator is given with special emphasis on the separation possibilities and ion number capabilities of the system.

Towards a "perfect" Penning trap mass spectrometer for unstable isotopes

1992

A Penning trap mass spectrometer has been set up at the on-line isotope separator ISOLDE/CERN for the mass determination of unstable heavy isotopes. The spectrometer should fulfil the following requirements: capture of external ions in high efficiency, high resolving power and accuracy, general applicability to all elements and isotopes available at the on-line facility.

Breakdown of the isobaric multiplet mass equation (IMME) at A=33, T=3/2

2000

Mass measurements on 3 3 , 3 4 , 4 2 , 4 3 Ar were performed using the Penning trap mass spectrometer ISOLTRAP and a newly constructed linear Paul trap. This arrangement allowed us, for the first time, to extend Penning trap mass measurements to nuclides with half-lives below one second ( 33 Ar : T 1 / 2 = 174 ms ). A mass accuracy of about 10 − 7 ( δ m ≈ 4 keV ) was achieved for all investigated nuclides. The isobaric multiplet mass equation was checked for the A = 33 , T = 3 / 2 quartet and found to be inconsistent with the generally accepted quadratic form. peerReviewed
