Abstract
A rotational band with seven gamma -ray transitions between states with spi n 2 (h) over bar and 16 (h) over bar has been observed in the doubly magic, self-conjugate nucleus Ca-40(20)20. The measured transition quadrupole mom ent of 1.80(-0.29)(+0.39)eb indicates a superdeformed shape with a deformat ion beta (2) = 0.59(-0.07)(+0.11). The features of this band are explained by cranked relativistic mean field calculations to arise from an 8-particle 8-hole excitation.
