  Angular radiation patterns of proton, deuteron or alpha emission are
evaluated using particle-in-cell simulation of laser induced nanoplasmonic
fusion. The differential Hanbury-Brown and Twiss analysis is widely used in
astrophysics and in relativistic heavy ion physics to determine the source size
of emitted particles. Here, we show how this method could be adopted for
inertial confinement fusion. This method aims to determine the parameters of
emitted nuclei after the fusion target ignition. In addition to spatial volume,
the method can detect specific space-time correlation patterns connected to the
collective flow post-ignition.
