TL;DR: Yield ratios for light particles and fragments with atomic number Z < or = 5 obey the exponential law of isotopic scaling, and deduced scaling parameters decrease strongly with increasing centrality to values smaller than 50% of those obtained for the peripheral event groups.

TL;DR: In this paper, the isotopic composition of intermediate mass fragments (IMF) emitted at midrapidity in semiperipheral collisions with the emission timescale is correlated to the symmetry energy term of nuclear equation of state at subsaturation densities.
