EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Addendum to the ISOLDE and Neutron Time-of-Flight Committee IS471: Collinear resonance ionization spectroscopy of rare francium isotopes
نویسندگان
چکیده
We propose to study the neutron-deficient (201−206Fr) and neutron-rich (218,219,229−232Fr) francium isotopes with high-resolution collinear resonance ionization spectroscopy. Extraction of the quadrupole moments will provide information on the nature of the deformation in the neutron-deficient nuclei and the octupole deformation suggested in the neutron-rich nuclei. The presence of the decay spectroscopy station will allow identification of any overlapping hyperfine structures. The high sensitivity of the CRIS technique will allow measurement of isotopes with low production yields, towards Fr and Fr. Requested shifts: 34 shifts

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Letter of Intent to the ISOLDE and Neutron Time-of-Flight Committee Benchmarking of a Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy of radionuclides
Supported by an ERC Starting Grant, we are developing a new experimental technique to enhance the sensitivity of collinear laser spectroscopy (CLS) by a factor 20-600 in order to probe rare isotopes currently out of reach due to their low production yields at radioactive ion beam (RIB) facilities. This novel approach is based on a multi-reflection time-of-flight apparatus (or also called electr...
متن کاملCollinear resonance ionization spectroscopy of neutron-deficient francium isotopes.
The magnetic moments and isotope shifts of the neutron-deficient francium isotopes (202-205)Fr were measured at ISOLDE-CERN with use of collinear resonance ionization spectroscopy. A production-to-detection efficiency of 1% was measured for (202)Fr. The background from nonresonant and collisional ionization was maintained below one ion in 10(5) beam particles. Through a comparison of the measur...
متن کاملCRIS: A new method in isomeric beam production
The Collinear Resonance Ionization Spectroscopy (CRIS) experiment at ISOLDE, CERN, uses laser radiation to stepwise excite and ionize an atomic beam for the purpose of ultra-sensitive detection of rare isotopes, and hyperfine-structure measurements. The technique also offers the ability to purify an ion beam that is heavily contaminated with radioactive isobars, including the ground state of an...
متن کاملEUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Proposal to the ISOLDE and Neutron Time-of-Flight Committee (19 October 2009) High-Precision Mass Measurements in the Rare-Earth Region to Investigate the Proton-Neutron Interaction
We propose precision mass measurements on a series of short-lived nuclides for the investigation of proton-neutron interactions and two neutron separation energies and their role in nuclear structure, especially concerning deformation and collectivity. The nuclides include neutron-rich Nd, Sm, Dy, Er, and Yb isotopes, as well as Hf. The investigations will require the Penning trap mass-spectrom...
متن کاملEUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Proposal to the ISOLDE and Neutron Time-of-Flight Committee The (n,α) reaction cross section measurement for light isotopes
We propose to measure the (n,α) reaction cross section for a set of light isotopes (16O, 10B, 12C, 14N, 19F) at the Experimental Area 1 (EAR-1) of the n_TOF neutron time of flight facility at CERN using gaseous targets. This will be the first time of time of flight measurement of the excitation function for these isotopes. The best resolution for incoming neutron energy can be reached. This rea...
