Abstract

We investigated the capture stage and successive nucleon transfer from the projectile to the target in the superheavy system ⁶⁴ ₂₈Ni + ²⁰⁷  ₈₂Pb (Z _proj. + Z _target = 110) . The target-like transfer products were detected at forward angles of (0±2) degrees, such, we selected nuclei resulting from central collisions. The data reveal several analogies to cold fusion reactions leading to superheavy elements. The observations are in accordance with the two-center shell model. The experiments have been performed at the velocity filter SHIP at GSI.
