particle.no: Particle indexing convention

In libamtrack: Computational Routines for Proton and Ion Radiotherapy

Description

The particle indexing system in libamtrack works as follows: for a particle with atomic number Z and mass number A the index is particle.no = 1000 * Z + A. This ensures uniqueness for all particle types used in libamtrack. Also, an extension to anti-protons or ions could be made using negative numbers.

Details

• For a proton (Z=1,A=1) particle.no is 1001.

• For deuterium (Z=1, A=2) particle.no is 1002.

• For He-4 (Z=2, A=4) particle.no is 2004.

• For C-12 (Z=6, A=12) particle.no is 6012.

• For a U-238 (Z=92, A=238) particle.no is 92238.

You can use AT.particle.name.from.particle.no and AT.particle.no.from.particle.name to convert particle names into particle indices and vice versa.
