Abstract

Intermediate-mass-fragment (IMF, 3 ≤ Z ≤ 20) emission probabilities and IMF charge distributions were recently shown to be reducible to the corresponding one fragment quantities. Furthermore, a strong thermal scaling was shown to control the energy dependence of the same quantities [1, 2, 3, 4].

    This software threshold is sufficiently low to integrate nearly all of the measured energy spectra. For larger thresholds (up to 5 MeV), the stated conclusions of this work remain unchanged but the azimuthal anisotropies become more pronounced.Google Scholar

    Note that the observed mass scaling is independent of the thermal scaling observed in Fig. 2. We merely use the linear slopes there to simplify our analysis of the mass scaling.Google Scholar
