Attempt to produce element 120 in thePu244+Fe58reaction

An experiment aimed at the synthesis of isotopes of element 120 has been performed using the $^{244}\mathrm{Pu}(^{58}\mathrm{Fe},\mathit{xn}){}^{302\ensuremath{-}x}120$ reaction. No decay chains consistent with fusion-evaporation reaction products were observed during an irradiation with a beam dose of $7.1\ifmmode\times\else\texttimes\fi{}{10}^{18} 330\text{\ensuremath{-}}\mathrm{MeV} {}^{58}\mathrm{Fe}$ projectiles. The sensitivity of the experiment corresponds to a cross section of 0.4 pb for the detection of one decay.
