DROSG-2000: Neutron Source Reactions

Data files with computer codes for 57 accelerator-based neutron source reactions

prepared by M. Drosg Institute for Experimental Physics, University of Vienna

v. 2.0: 17-NOV-2000, IAEA-NDS-87 Rev. 6, January 2001

UPDATES:

!: VERSION 2.0: 17-NOV-2000

Code was made compatible with LAHEY-FORTRAN for LINUX.

a) Major changes were necessary to maintain "default" capabilities.

Subroutine NDEFLT has now 5 arguments so that it can handle an input pair.

b) All commas (used for data separation) in data files (*.KOE, *.tab) were

removed. As a consequence a few FORMAT changes were necessary.

c) To avoid warnings during compilation none of the COMMON blocks (in all the

subroutines) is truncated any more and dummy variables were removed.

d) No capital letters for file names (UNIX!) in the calling routines any more.

e) A new reaction was added: 9Be(d,n)10B

f) A new target type (LiF) was added for the 7Li(p,n) reactions.

!

!: VERSION 1.01: 19-MAR-2000

a) Clean-up of COMMON blocks: CHARA

b) Several redundancies removed, e.g. in ANGSET: redundancy concerning

'LOW energy group OPTION= 1:' removed

c) Several FORMATS changed to allow much smaller values, e.g. in OUTPUT of

NYIOUT.F90: FORMAT 185 and 186

d) in BELTHR check for XXC=0. before /XXC

e) introduced minimum energy step number for WHIYIE

f) new flag LGERR avoids output of negative cross sections

g) added subroutine SPCAVG for WHIYIE

!

!: VERSION 1.0, 1999-12-31: DROSG-2000 supersedes DROSG-96 and DROSG-87.

All iteration routines were changed. They are based now on

physical properties so that no divergence should occur under any

condition. Besides any iteration occurs within about 20 steps

increasing the speed in some cases considerably. No more single

precision values.

In addition neutron production by (alpha,n) reactions was

added.

1999-08-12: VERSION 2.01 of DROSG-96 generated:

Automatic exit from the WHIYIE energy chain introduced, some error

conditions added.

1999-07-07: VERSION 2.0 of DROSG-96 generated:

1) improved near threshold yield calculations in WHIYIE to give

yields for both energy groups in forward direction

a) normal double-value operation at all lab angles

(CM angle iteration may fail very close to the one-value

threshold)

b) 0 degree option: input of 180 deg CM gives the yields of

the second zero degree group for ALL projectile energies as

long as the neutron energy is > 1.e-9 MeV.

2) improved tables:

a) cross sections for 3H(p,n)3He below 3.2 MeV include recent

results by BRUNE et al. and below 1.8 MeV a recent

(preliminary) R-matrix solution by HALE.

b) cross section table P7LIGS.KOE for 7Li(p,n)7Be improved

by some interpolated values

c) energy loss in hydrogen extended to lower energies

d) increased number of digits in MASS.TAB

e) edtiting changes in SETYIE.TAB

1997-02-18: Modularity of the code increased by extracting several SUBROUTINES

from lengthy code portions.

 

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!*

!* The package DROSG-2000 distributed by IAEA-NDS consists of 3

!* executable Programs:

!*

!* 1) NEUYIE: Mononenergetic neutron production

!* This program calculates neutron energies and differential cross

!* sections for monoenergetic neutron sources from internal tables

!* of the Legendre coefficients (stored in files *.KOE).

!* For isotopic pure target (and others) it also can calculate the

!* neutron yield using the energy loss tables in the files *.ELS.

!* The neutron yields are given for an energy loss of the projectile

!* that results in a 10 keV neutron energy spread at 0 degree.

!*

!* 2) WHIYIE: White neutron yields from two-body reactions

!* This program calculates thick target yields of white neutron sources

!* that are based on the two-body reactions covered under 1).

!* As an option, a white spectrum ready for plotting is produced.

!*

!* 3) TIMREV: Cross sections and energies of (n,p), (n,d), (n,t) and

!* (n,alpha) reactions are calculated by detailed balance from the time

!* reversed reactions covered under 1).

!*

!* The PROGRAMS are written in FORTRAN which is fully compatible with

!* standard FORTRAN-90. They run under OPEN-VMS or VMS of DEC computers

!* and under MS-DOS on standard PCs when compiled with a LAHEY F77L or a

!* F90 compiler.

!* EXECUTABLES are provided to run under OPEN-VMS (*.exe for VAXes,

!* *.e90 for ALPHAs), under LINUX for PCs and under MS-DOS (NEUTRF77.EXE

!* should run on any standard PC, even without ARITHMETIC COPROCESSOR,

!* NEUTRF90.EXE, the FORTRAN-90 version, requires at least a 386 processor).

!* The FORTRAN-90 versions are about 30% faster.

!*

!*

!* A provision for generating plot files of excitation functions is

!* included, by selecting energies from the cross section tables to

!* avoid iteration errors which tend to occur in cases with a strong

!* structure in the energy dependence of the cross sections.

!*

!* The regular O U T P U T of all three codes is in File FOR002.DAT.

!* It will be overwritten each time.

!*

!* WHIYIE can produce, in addition, a spectrum *.SPC which will be

!* overwritten if the complete filename equals a previous one.

!* FOR001.DAT contains data that may be used for integration over

!* energy and/or angle.

!*

!*

!* These codes were written by

!* M. DROSG,

!* INST. F. EXP. PHYSICS OF THE UNIVERSITY OF VIENNA,

!* STRUDLHOFG. 4, A-1090 WIEN, AUSTRIA FOR HIS PERSONAL USE.

!* NEITHER THE AUTHOR NOR ANYBODY ELSE MAKES ANY WARRANTY, EXPRESS OR

!* IMPLIED, OR ASSUMES ANY LEGAL LIABILITY OR RESPONSILBILITY FOR THE

!* ACCURACY, COMPLETENESS OR USEFULNESS OF THIS PROGRAM AND OF RESULTS

!* OBTAINED BY IT, OR REPRESENTS THAT ITS USE WOULD NOT INFRINGE

!* PRIVATELY OWNED RIGHTS.
