Laser induced Coulomb explosions give precise information on the masses of the clusters released in the quantised kinetic energy release (KER) in an electronically excited phase Rydberg Matter (RM). A model is given that describes the non-trivial variations of time-of-flight (TOF) with detector angle as due to the spatial origin of the clusters. Three types of TOF peaks are identified: from the laser waist, from the region along the laser beam and from the edge of the blow-out cone at which a shock wave is initiated. Cluster masses and KER energies can be accurately assigned using this model. RM clusters ( H 2 ) 14 ∗ and K N ∗ ( N = 1 , 2 , 4 , 7 ) are confirmed, and a new cluster H 7 ∗ is identified. At low laser levels, large fluctuations in signal intensities from the laser waist are observed, proving that the phase sampled is not gaseous but fractal in nature.
