Testing of SRIM and MSTAR computer codes from the point of view of reciprocity principle Draft Introduction Introduction A key quantity which determines changes of the properties is the stopping power.
Testing of SRIM and MSTAR computer codes from the point of view of reciprocity principle Draft Introduction Introduction A key quantity which determines changes of the properties is the stopping power. At present, there is no reliable theory for calculating the electronic stopping power in low velocity regime.

At present, there is no reliable theory for calculating the electronic stopping power in low velocity regime. As a guidance in obtaining the electronic stopping powers at low energies, the principle of reciprocity has been proposed recently by Sigmund [Eur. Phys. J. D 47, 4554 (2008)].

As a guidance in obtaining the electronic stopping powers at low energies, the principle of reciprocity has been proposed recently by Sigmund [Eur. Phys. J. D 47, 4554 (2008)]. The aim of this project is to check the correspondence of predictions obtained from most widely used computer codes, SRIM and MSTAR, to the principle of reciprocity.

Testing of SRIM and MSTAR computer codes from the point of view of reciprocity principle Draft Reciprocity principle Reciprocity principle The reciprocity principle states that the electronic stopping cross section is the same whether projectile A with a velocity v hits the target B or the projectile B with the same velocity v hits target A.
Testing of SRIM and MSTAR computer codes from the point of view of reciprocity principle Draft Reciprocity principle Reciprocity principle The reciprocity principle states that the electronic stopping cross section is the same whether projectile A with a velocity v hits the target B or the projectile B with the same velocity v hits target A. In order to use the principle of reciprocity one needs to subtract the nuclear stopping power from the total stopping power measured in an experiment.

In order to use the principle of reciprocity one needs to subtract the nuclear stopping power from the total stopping power measured in an experiment. The reciprocity principle has been extensively checked against comprehensive data collection by Helmut Paul [http://www.exphys.jku.at/stopping/], which collects stopping data for ions, targets and beam energies from literature.
