# Gamma and electron spectroscopy of heavy nuclei at FLNR JINR

Abstract : Detailed spectroscopic information of excited nuclear states in deformed transfermium nuclei is scarce. Most of the information available today has been obtained from investigations of fine structure $\alpha$ decay. Although $\alpha$ decay gives access to hindrance factors and lifetimes which are strongly correlated to shell/subshell closures and the presence of isomers, only the combined use of $\gamma$ and conversion electron spectroscopy allows the precise determination of excitation energy, spin and parity of nuclear levels. In particular, the study of odd isotopes gives crucial information on the single particle states available at and around the Fermi surface. In the following, the preliminary results of decay studies using $\alpha - \gamma$ and $\alpha - \beta$ coincidences at the focal plane of the VASSILISSA recoil separator are presented.
