(a) Difference scattering function ΔS(Q)Q2 for a set of different laser fluences for a 300 ps delay. With increasing fluence the maximum shifts to lower Q. The scattering is weighted by Q2 in order to amplify the modulations at high Q. (b) Simulations of the curves above for adapted density distributions in a core–shell system. The inset shows the radius of the vapor bubble around the particles as a function of laser fluence. At a fluence below 150 J m−2, no bubbles are seen. |
