Charge – Changing Cross Sections (CCCS) code
The CCCS code allows to estimates the charge-changing cross sections for gaseous and solid targets and to calculate equilibrium charge state fractions and charge-changing energy losses. The charge-changing cross section σ q,k (E,Z,Z t ) is the sum over all cross sections of processes in which the ion with charge q transformed into ion with the charge k. The indices q and k in can range from -1 (if the negative ion exists) to nuclear charge of the projectile Z. The present version of code (CCCS-2015) allows to estimate cross sections for the nuclear charge of the projectile Z (5 ≤ Z ≤ 18) and the nuclear charge of the target atom Z t (Z t ≤ 99) in energy E range from 0.001 up to 100 MeV/amu.Download cccscode.zip (370 kb):
