[en] The resonance tunneling via lattice-confined ion is quite different from that of beam-target nuclear reaction. Because of the coulomb barrier, only the long life-time nuclear energy level has the chance to be in resonance with the lattice-confined ion. As a result, fast nuclear fusion with a strong neutron radiation can not be induced by this kind of resonance tunneling. It means that obtaining the nuclear fusion energy without the strong neutron radiation is possible
