TL;DR: A search for superheavy elements was made in bombardments of $€ 1.5 billion with ions performed at projectile energies close to the interaction barrier in order to keep the excitation energy of the compound nucleus $Z=116, $A=296$ as low as possible as mentioned in this paper.
Abstract: A search for superheavy elements was made in bombardments of $^{248}\mathrm{Cm}$ with $^{48}\mathrm{Ca}$ ions performed at projectile energies close to the interaction barrier in order to keep the excitation energy of the compound nucleus $Z=116$, $A=296$ as low as possible. No evidence for superheavy nuclei was obtained in a half-life region from 1 \ensuremath{\mu}s to 10 yr with a production cross section greater than ${10}^{\ensuremath{-}34}$ to ${10}^{\ensuremath{-}35}$ ${\mathrm{cm}}^{2}$.
