By means of the adiabatic self-consistent collective coordinate method andthe pairing plus quadrupole interaction, we have obtained the selfconsistentcollective path connecting the oblate and prolate local minima in 68Se for thefirst time. Along the collective path, the triaxial deformation parameter(gamma) changes between 0 and 60 (degree) keeping the axially symmetricdeformation parameter (beta) approximately constant, indicating the importanceof triaxial deformation dynamics in the oblate-prolate shape coexistencephenomena.Comment: 6 pages including 6 eps figure
