Abstract
\ensuremath{\mathsf{^{74}Ge}} beam was Coulomb-excited on a \ensuremath{\mathsf{^{nat}Pb}} target. Ten E2 matrix elements including diagonal matrix elements for 5 low-lying states have been determined using the least-squares search code GOSIA. The expectation values of the rotational invariants $\langle Q^2$$\rangle$ and $\langle$cos3$\delta$$\rangle$show the small and triaxial deformation of the two lowest members of the ground-state band , while the 02+ and 22+ states are found to be almost spherical.
