IAEA1282 ESTAR/PSTAR/ASTAR.

1. NAME OR DESIGNATION OF PROGRAM:  ESTAR/PSTAR/ASTAR.

3. DESCRIPTION OF PROGRAM OR FUNCTION

ESTAR - calculates for electrons: electronic, radiative, and total mass stopping power; CSDA range; radiation yield.
PSTAR - calculates for protons: electronic, nuclear, and total mass  stopping power; CSDA range; projected range; detour factor.
ASTAR - calculates for alphas: electronic, nuclear, and total mass stopping power; CSDA range; projected range; detour factor.

4. METHOD OF SOLUTION

ESTAR - electronic mass stopping powers are calculated from the theory of Bethe. Radiative stopping powers are evaluated with a
combination of theoretical bremsstrahlung cross sections described by Seltzer and Berger. Analytical formulas are used above 50 MeV, and numerical results below 2 MeV. Interpolation is done in the intermediate range.
PSTAR and ASTAR - Both programs rely on interpolation in a database  of stopping powers and ranges.

11. MACHINE REQUIREMENTS:

The program has been installed at NEA-DB on a DELL-466/L PC/80486 (67 MHz) with 16 Mbytes of RAM.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:

The tests were run at NEA-DB under MS-DOS 6.2. The source programs were compiled using the Lahey F77L-EM/32 Fortran-77  compiler Version 5.20.
