Abstract

The hot fusion reaction ${}^{48}$C + ${}^{238}$U is studied with time-dependent Hartree-Fock theory in combination with coupled-channels and fusion-by-diffusion models. The authors find that the fusion probability is strongly dependent on the orientation of the ${}^{238}$U nucleus, with the probability being greatest for the tip collision orientation. This understanding will be applied in the future to determine optimal target and projectile combinations for the synthesis of elements $Z=119$ and 120.
