The yrast level structure of 215,216Rn has been studied using in beam spectroscopy α-γ-γ coincidence techniques mainly through the 207Pb(18O, 2α2n) and 208Pb(18O, 2α2n) reactions in the 91-93 MeV energy range, using the 8π GASP-ISIS spectrometer at Legnaro. The obtained low lying level scheme of 215Rn does not exhibit the alternating parity structure observed in their heavier known isotones 216Fr, 217Ra and 218Ac. The level scheme of 216Rn resulting from this study shows. From this result, the lightest nucleus showing evidence for reflection asymmetry is 216Fr defining one lowest-mass corner for this kind of phenomenon as N > 129 and Z > 87.
