| contents | Low-energy fusion of heavy ions is a fascinating coupling-assisted quantum tunnelling problem, whose understanding is crucial for advancing the synthesis of new elements and isotopes. Quantum dynamical coupled-channels calculations of laser-assisted $^{16}$O + $^{238}$U fusion are presented for both a central collision and the total fusion cross-sections, suggesting that laser-nucleus interaction can enhance the average $^{16}$O + $^{238}$U fusion probability by $6-60 \%$ at subbarrier energies using quasi-static laser fields of intensity $10^{27}-10^{29}$ Wcm$^{-2}$ and photon's energy of $1$ eV. Femtosecond laser pulses are shown to reduce this enhancement by many orders of magnitude. |
