3. DESCRIPTION OF PROGRAM OR FUNCTION

DCHAIN calculates the time-dependent daughter populations in radioactive decay and
nuclear reaction chains. Chain members can have non-zero initial populations and be produced from the preceding chain member as the result of radioactive decay, a nuclear reaction, or both. Parent-daughter equilibrium times and relative activities at equilibrium can also be calculated. Program input can be supplied interactively or read from ASCII data files. Chain members can have non-zero initial populations and be produced from the preceding chain  members  as the result of radioactive decay, a nuclear reaction, or both. Extensive on-line help is available by entering "?" or "help" on response to any input request.

4. METHODS

The calculation method involves solving a generalized form of the Bateman equations.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Default configuration limits the number of decay/reaction chain members to 15 (this can be changed by editing a configuration parameter and recompiling). Results must be saved in a file in order to  obtain hard-copy output.

6. TYPICAL RUNNING TIME

DCHAIN is interactive. Results are essentially instantaneous.

11. HARDWARE REQUIREMENTS

  The included executable is for use  on personal computers running  DOS  V2.1 or higher. The code  may be recompiled on any computer which has  an  ANSI C capable compiler. The "character" user interface should be  compatible with any computer terminal or terminal emulator (support of ASCII escape sequences is not required). Memory requirements are minimal; less than 100KB under MS-DOS.

13. SOFTWARE REQUIREMENTS

An ANSI C compiler is required. An executable file is supplied for use on personal computers running MS/PC-DOS V2.1 or later. The program can be recompiled to run on any platform that supports ANSI C. To date, it has been compiled and tested on the following systems:
- MS-DOS V4.0 and V.6.2 using Microsoft C V6.0 and QuickC       V2.5
- VAX/VMS V5.x and V6.0 using VAX C V3.1
- Open VMS/AXP V1.5 using DEC C V1.3
- ULTRIX V4.3 using MIPS Systems C V2.10
- DG/UX Release 5.4R2.01 using GNU C V2.3.3
- IBM/AIX V3.2.5 using XLC Compiler
