The heavy actinide nucleus 253No (Z = 102) was studied using the (S)ilicon (A)nd (Ge)rmanium (sage) spectrometer allowing simultaneous in-beam γ-ray and conversion electron spectroscopy at the accelerator laboratory of the University of Jyv¨askyl¨a. Using the recoil-tagging technique, γ-electron coincidences have allowed for the extension of the level scheme in the lower-spin region of the yrast band. In addition, internal conversion coefficient (ICC) measurements to establish the multipolarity of transitions have been performed. Measurement of the interband-intraband branching ratios supports the assignment of the Nilsson band-head configuration 9/2− assigned in previous studies. The study shows the viability of combined in-beam electron and γ-ray spectroscopy down to μb cross sections.
