This contribution will be divided into two parts. In the first part I will describe experimental attempts to determine the sign of the electric dipole moment (relative to the electric octupole moment) in the octupole deformed nucleus 226Ra. Sensitivity to this quantity is observed in the measured yields of $\gamma$-ray transitions following very low energy Coulomb excitation.

In the second part I will report on recent progress in the development of new spectroscopic techniques that promise to elucidate the structure of deformed superheavy nuclei in the region of 254No. The $4^+ \rightarrow 2^+$ transition in 254No has been identified using recoil-tagged conversion electron spectroscopy. This technique has been applied to the measurement of the strongly converted rotational bands in 253No.

Both experimental projects have been carried out by a collaboration between the University of Liverpool and the University of Jyväskylä at the Jyväskylä cyclotron laboratory.
