A rotational band with five cascade $$gamma$$-ray transitions was newly found in $$^{40}$$Ar. The deduced transition quadrupole moment of $$1.45^{+0.49}_{-0.31}$$ eb has demonstrated this band as having a superdeformed shape of $$beta_2 sim$$ 0.5. The structure of the band was discussed in the framework of cranked Hartree-Fock-Bogoliubov calculations and the assignment of multiparticle-multihole configuration has been made.
