Isotopic Ratio, Isotonic Ratio, Isobaric Ratio and Shannon Information Uncertainty [PDF]

open access: yesCommunications in Theoretical Physics, 2014
The isoscaling and the isobaric yield ratio difference (IBD) probes, which both are constructed by yield ratio of fragment, provide cancelation of parameters. The information entropy theory is introduced to explain the physical meaning of the isoscaling and IBD probes.
