Laser spectroscopy of francium isotopes at the borders of the region of reflection asymmetry / Budinčević, I. (KU Leuven, Dept. Phys. Astron.) ; Billowes, J. (Manchester U.) ; Bissell, M.L. (KU Leuven, Dept. Phys. Astron.) ; Cocolios, T.E. (Manchester U.) ; de Groote, R.P. (KU Leuven, Dept. Phys. Astron.) ; De Schepper, S. (KU Leuven, Dept. Phys. Astron.) ; Fedosseev, V.N. (CERN) ; Flanagan, K.T. (Manchester U.) ; Franchoo, S. (Orsay, IPN) ; Garcia Ruiz, R.F. (KU Leuven, Dept. Phys. Astron.) et al.
The magnetic dipole moments and changes in mean-square charge radii of the neutron-rich $^{218m,219,229,231}\text{Fr}$ isotopes were measured with the newly-installed Collinear Resonance Ionization Spectroscopy (CRIS) beam line at ISOLDE, CERN, probing the $7s~^{2}S_{1/2}$ to $8p~^{2}P_{3/2}$ atomic transition. The $\delta\langle r^{2}\rangle^{A,221}$ values for $^{218m,219}\text{Fr}$ and $^{229,231}\text{Fr}$ follow the observed increasing slope of the charge radii beyond $N~=~126$. [...]

Collinear Resonance Ionization Spectroscopy of Neutron-Deficient Francium Isotopes / Flanagan, K T (Manchester U.) ; Franchoo, S (Orsay, IPN) ; Ruiz, R F Garcia (Leuven U.) ; Budincevic, I (Leuven U.) ; Procter, T J (Manchester U.) ; Fedosseev, V N (CERN) ; Lynch, K M (Manchester U. ; CERN) ; Cocolios, T E (Manchester U. ; CERN) ; Marsh, B A (CERN) ; Neyens, G (Leuven U.) et al.
The magnetic moments and isotope shifts of the neutron-deficient francium isotopes Fr202-205 were measured at ISOLDE-CERN with use of collinear resonance ionization spectroscopy. A production-to-detection efficiency of 1\% was measured for Fr-202. [...]

The Collinear Resonance Ionization Spectroscopy (CRIS) experimental setup at CERN-ISOLDE / Cocolios, T E (Manchester U. ; CERN) ; Neyens, G (Louvain U.) ; Procter, T J (Manchester U.) ; Rothe, S (CERN ; Mainz U., Inst. Phys.) ; Garcia Ruiz, R F (Louvain U.) ; Stroke, H H (New York U.) ; Rossel, R E (CERN ; Mainz U., Inst. Phys.) ; Heylen, H (Louvain U.) ; Franchoo, S (Orsay, IPN) ; Marsh, B A (CERN) et al.
The CRIS setup at CERN-ISOLDE is a laser spectroscopy experiment dedicated to the high-resolution study of the spin, hyperfine structure and isotope shift of radioactive nuclei with low production rates (a few per second). It combines the Doppler-free resolution of the in-flight collinear geometry with the high detection efficiency of resonant ionisation. [...]

A dedicated decay-spectroscopy station for the collinear resonance ionization experiment at ISOLDE / Rajabali, M.M (Leuven U.) ; Billowes, J (Manchester U.) ; Bissell, M.L (Leuven U.) ; Cocolios, T.E (CERN) ; De Schepper, S (Leuven U.) ; Dewolf, K (Leuven U.) ; Flanagan, K.T (Manchester U.) ; Le Blanc, F (Orsay, IPN ; Orsay, LPT) ; Lynch, K.M (Manchester U ; CERN) ; Marsh, B.A (CERN) et al.
A new decay-spectroscopy station (DSS) has been developed to be coupled to the collinear resonance ionization spectroscopy (CRIS) beam line at CERN-ISOLDE. The system uses a rotatable wheel with ten 20@mg/cm^2 carbon foils as beam implantation sites for the efficient measurement of charged decay products. [...]

This paper reports on the hyperfine-structure and radioactive-decay studies of the neutron-deficient francium isotopes $^{202-206}$Fr performed with the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at the ISOLDE facility, CERN. The high resolution innate to collinear laser spectroscopy is combined with the high efficiency of ion detection to provide a highly-sensitive technique to probe the hyperfine structure of exotic isotopes.
