A rotational band with five γ-ray transitions ranging from 2+to 12+states was identified in40Ar. This band is linked through γ transitions from the excited 2+, 4+and 6+levels to the low-lying states; this determines the excitation energy and the spin–parity of the band. The deduced transition quadrupole moment of 1.45−0.31+0.49±0.15 eb indicates that the band has a superdeformed shape. The nature of the band is revealed by cranked Hartree–Fock–Bogoliubov calculations and a multiparticle–multihole configuration is assigned to the band.
