General Comments:

2010Ch16: measurement of spin and static magnetic and quadrupole moment hyperfine spectra at ISOLDE-CERN using collinear laser spectroscopy. Deduced spin, magnetic moment and quadrupole moment. Comparison with shell-model calculations.

2012Pr11: U(p,X),E(p)=1.4 GeV incident on UCx target at ISOLDE-CERN facility. Fragments diffused out of target and surface ionized, then accelerated to 30 keV, followed by mass separation and bunched by gas-filled Paul Trap (ISCOOL). Isotope shifts were measured by collinear laser spectroscopy using COLLAPS setup at ISOLDE-CERN. Deduced rms charge radius.

Mass measurement: 2008Ha23, 2008Su19

Nuclear structure calculations: 2015Ka46, 2012Ve03, 2011Ji08, 2008Yo07: calculated levels, J, π

Q-value: S(2n)=12698 3, S(2p)=28610 150 (syst), Q(β-n)=1243 4 (2012Wa38)

Jπ(level): The log ft values from (9/2+) are in the range 5.4 to 6.4 for most of the excited states. This would limit spins to (7/2,9/2,11/2) for many levels above 1000

-n: weighted average given by 1993Ru01 of the following values: 0.113 11 (1993Ru01), 0.055 12 (1986Wa17), 0.098 16 (1980Lu04). The uncertainty given by 1986Wa17 is 0.004 and that by 1980Lu04 is 0.010. 1993Ru01 seem to have increased these uncertainties in obtaining weighted average. Other: 0.10 1 (1984Ma39,compilation).
