## Spectroscopy of element 115 decay chains

The full document is not yet published but a paper accepted 7 Aug 2013 entitled Spectroscopy of element 115 decay chains by D. Rudolph et al. provides additional evidence for element 115:

A high-resolution $\alpha$, $X$-ray and $\gamma$-ray coincidence spectroscopy experiment was conducted at the GSI Helmholtzzentrum f\"ur Schwerionenforschung. Thirty correlated $\alpha$-decay chains were detected following the fusion-evaporation reaction $^{48}$Ca~+~$^{243}$Am. The observations are consistent with previous assignments of similar decay chains to originate from element $Z=115$. For the first time, precise spectroscopy allows the derivation of excitation schemes of isotopes along the decay chains starting with elements $Z>112$. Comprehensive Monte-Carlo simulations accompany the data analysis. Nuclear structure models provide a first level interpretation.
