Heavy-Ion Dosimetry

open access: yes, 1980
A comprehensive and accurate definition of the physical characteristics of a radiation field is a necessary, but not sufficient, condition for understanding (and predicting) the probability of observing a biological effect. Part of the difficulty of doing this stems from the fact that very often the biological final state accessible to observation is ...

Heavy Ion Collisions

open access: yes, 2004
Lattice QCD predicts a phase transition between hadronic matter and a system of deconfined quarks and gluons (the Quark Gluon Plasma) at high energy densities. Recent results from the Brookhaven Relativistic Heavy Ion Collider (RHIC) dedicated to the study of QCD at extreme densities will be discussed and compared to measurements obtained at the CERN ...

Pionic Fusion of Heavy Ions [PDF]

open access: yesPhysical Review Letters, 1996
We report the first experimental observation of the pionic fusion of two heavy ions. The 12C(12C,24Mg)pi0 and 12C(12C,24Na)pi+ cross sections have been measured to be 208 +/- 38 and 182 +/- 84 picobarns, respectively, at E_cm = 137 MeV. This cross section for heavy-ion pion production, at an energy just 6 MeV above the absolute energy-conservation ...
