The high-spin spectrum of /sup 84/Zr is studied using the Strutinsky-Bogolyubov cranking model with a Woods-Saxon average potential. Calculations explain observed irregularities in the /sup 84/Zr yrast line in terms of band crossings involving aligned g/sub 9/2/ proton and neutron bands. A transition to the superdeformed shape is predicted to occur around Iapprox.30h-dash-bar. Experimental data are consistent with the nucleus having a well deformed (..beta../sub 2/approx. =0.3) and triaxial (..gamma..approx. =-20/sup 0/) shape.
