3. DESCRIPTION OF PROGRAM OR FUNCTION

STOPOW calculates a set of stopping power values and ranges of fast ions in matter for any materials. Furthermore STOPOW can calculate a set of values for one  special auxiliary function (e.g. kinematic factors, track structure  parameters, time of flight or correction factors in the stopping function). The user chooses the physical units for stopping powers and ranges and the energy range for calculations.

4. METHOD OF SOLUTION

The program uses the method of ZIEGLER et al. with user-defined non-relativistic and relativistic corrections in the energy range up to 100 MeV/amu. For higher energies the treatment of AHLEN is used. The program calculates the stopping power and ranges for an energy grid with logarithmic equally-spaced  steps. These values are given as arrays, printing tables or output files.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Ions from H up to super heavies and compound targets with up to 30 different atomic constituents may be considered. The target compound can also contain up to five sub-compounds. This means the target is 1 keV/amu - 10 GeV/amu. Maximum incident energy can easily be increased by increasing the storage area. The program gives reasonable values up  to 100 GeV/amu, it has not been tested for higher energies. The program accepts all the elements up to uranium, and for the input of a special target element identification of the element by atomic number is all that is needed. Batch and interactive input is  possible.

6. TYPICAL RUNNING TIME

Problem dependent. For 183 logarithmic equally-spaced energies and a five-element target, a few CPU seconds on ES 1055m/56 computers. On a 16-bit PC with 8087 arithmetic processor, about 10 - 20 seconds.
