| 970 | (5/2-,7/2-) | E(level): Ground-state band. Jπ(level): Proposed from shell-model calculations (2009Ri11). | |
| 1153 | (5/2-,7/2-) | E(level): Ground-state band. Jπ(level): Proposed from shell-model calculations (2009Ri11). | |

| E(level) | E(gamma) | Comments |
| 320.7 | 320.7 | E(γ): from 43S IT decay M(γ): for mult=M1 or E1, deduced hindrance factors are unrealistically large. Mult=E2 would be compatible with the measured lifetime |
First identification of 43S nuclide by 1979We10
43S isotope produced and identified in 9Be(48Ca,X) E=212 MeV/nucleon (1979We10); 181Ta(48Ca,X) (1989Le16) and Th(p,X) E=800 MeV (1991Zh24), followed by measurement of fragment spectra. Measured (1989Le16) %β-n, T1/2
2012Ch16: TDPAD method used to measure spectroscopic quadrupole moment of 7/2- isomeric state of 43S at 320.5 keV. E=345 MeV/nucleon beam produced at RIKEN-RBF facility using BigRIPS spectrometer for fragment separation. 43mS fragments were selected and implanted in Cu host. The g factor was first measured to validate the method. The 320.5-keV γ-ray was measured using four HPGe detectors. Time spectrum of each detector was used to generate R(t) function
