Аннотация:
The principle of reciprocity in the electronic stopping of slow ions in matter gives researchers a clear and powerful criterion for testing of reliability of experimental data as well as stopping theories and models. Moreover, the principle allows to determine missing stopping cross section S(Y-> X) upon condition a credible S(X -> Y) is available.
A computer code REST has been developed to facilitate a cumbersome compilation, analysis and visualization of data from various data sets. This work pre-sents a new extended version of the code.
Improvements include:

A computer code REST has been developed to facilitate a cumbersome compilation, analysis and visualization of data from various data sets. This work pre-sents a new extended version of the code.
Improvements include:
- all elements of Paul’s database can be analyzed;
- classic theories by Lindhard & Scharff and by Firsov are implemented;
- PASS stopping database can be examined;
- user’s database can be appended to Paul’s one;
- the code provides a statistical analysis of available data;
- up to four additional data sets can be included into plots;
- the current version of REST utilizes dynamically allocated objects to reduce computer memory usage.
