Intensity interferometry and imaging techniques will be presented as tools to probe the space-time properties of nuclear reactions [1]. Applications to p-p correlation functions measured in collisions at E/A=50-150 MeV will be shown to disentangling fast pre-equilibrium and slow evaporative emissions [1]. The profile (space-time image) of the emitting source also probes nuclear transport properties and the density dependence of the symmetry energy, relevant to both nuclear physics and astrophysics [2]. The extension of the technique to complex particles will also be discussed [3].
Correlation techniques are also used to access spectroscopic properties of unbound nuclei [4]. An application to the sequential and simultaneous decay of unbound states of 10C into two protons and two alphas will be described [4]. This study shows that these techniques can provide tools to access the dynamics and spectroscopy of exotic nuclei, an interesting perspectives for future radioactive beam facilities.
