Abstract

A search for superheavy elements was made in bombardments of Cm248 with Ca48 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.
