Abstract On the basis of coupled neutronic/hydrodynamic calculations, we examine the neutron heating effects in the ignition and burn phases of the laser imploded D-T pellets. The neutrons deposit their energy all around the pellet, since the mean free path of neutron is long. The fraction of neutron energies deposited to the central spark region in the ignition phase is too small to reduce the threshold energy of laser for ignition. In the burn phase, the neutron heating decreases the maximum compression ratio and accelerates the plasma expansion. The inclusion of neutron heating then decreases the pellet gain from the value in the case of neglecting the neutron heating. {copyright} {ital 1996 American Institute of Physics.}
