General Comments:

First identification of 43Ar nuclide by 1969Ha03

1971Ar32: 232Th(40Ar, X), E=290 MeV; measured fragments isotopic yields

2005Bl33: measured charge radii

2007Na31: 136Xe(p,X) production cross sections.

Mean-square radius from energy-integrated cross sections: 1999Ai02, 1997Li15

Mass measurements: 2001He29

2008Bl01: mass-separated 43Ar ion beam obtained from spallation of Ti by 1.4 GeV beam provided by CERN synchrotron followed by on-line mass separation at ISOLDE-CERN facility. Measured spins, isotope shifts, hyperfine structure, mean-square charge radii, magnetic dipole and electric quadrupole moments by fast beam collinear laser spectroscopy using highly sensitive ion detection of optical resonance. Comparisons with spherical Skyrme-type Hartree-Fock mean-field calculations.

Structure calculations: 2011Ka03, 2007Sh10, 1991Wa19, 1987Sa19, 1974Gl04

Q-value: S(2n)=15085 5, S(2p)=27579 7 (2012Wa38).
