PyAtima is a python wrapper for the program Atima [1] which is used for the calculation of the slowing down of ions in matter.
PyAtima expects that Atima can be invoked from the command line by calling
atimawww {input}
with the appropriate input.
PyAtima can be obtained by cloning this repository to the local system and running
python3 setup.py install
in the command line.
PyAtima expects the same input quantities as Atima:
- Zp: Proton number of projectile.
- Ap: Mass number of projectile.
- E: Energy of projectile [MeV/u].
- Zt: Proton number of target.
- At: Molar mass of target [u].
- t: Target thickness [mg/cm2].
For instance, the stopping of 64Fe ions at 100 MeV/u in 100 mg/cm2 of beryllium is calculated via
import PyAtima as pa
atima = pa.PyAtima(Zp=26,Ap=64,E=100,Zt=4,At=9.01,t=100)
Results of the calculation are stored in the dictionary
atima.results
