Downloading RadWare Level Schemes

In addition to the RadWare software, this site also hosts a compilation of nuclear level scheme files in the RadWare ASCII-gls format, for use in gls, escl8r, levit8r, dixie_gls etc. You can view and/or get these level schemes most easily through the level scheme directory script, but also by pointing your browser at ftp://radware.phy.ornl.gov/pub/nd/.
If you prefer to use ftp from outside your web browser, you can follow the instructions given below.

The level scheme files all end in the suffix ".ags" (for Ascii Graphical level Scheme). Accompanying each .ags file is a .txt plain text file, that contains information about the level scheme file and how it was generated or obtained.

The files are grouped in directories according to the Mass Number, A. For example, you can find the files for 40Ca (Calcium-40) in the subdirectory 040 of the pub/nd directory, and for 102Pd (Palladium-102) in the subdirectory 102.

To illustrate the file naming conventions, the current files for 102Pd are:

   102Pd_ensdf_A.ags
   102Pd_ensdf_A.txt
   102Pd_ensdf_CE.ags
   102Pd_ensdf_CE.txt
   102Pd_ensdf_HI_xng.ags
   102Pd_ensdf_HI_xng.txt
   102Pd_ensdf_misc01.ags
   102Pd_ensdf_misc01.txt
   102Pd_jg.ags
   102Pd_jg.txt

The files containing _ensdf_ are all generated by conversion from the Evaluated Nuclear Structure Data File (ENSDF). Filenames with _A indicate that the file contains Adopted levels and gammas, _CE indicates data from Coulomb Excitation, and _HI_xng indicates data from (HI,xng) reactions.

The 102Pd_jg files were contributed, in this case by Jean Gizon.


Important Note on ENSDF Level Schemes

PLEASE NOTE that the RadWare-format files given on this site cannot preserve, in any strict sense, the careful data assignments made by nuclear data evaluators and stored in the ENSDF files. The RadWare format is much more limited than the ENSDF format; for example, in RadWare, transition multipolarities are deduced from the level spins and parities, while in ENSDF a transition may have no multipolarity assigned, or one assigned in a range of different ways. Likewise, other quantities required by the RadWare format may or may not be assigned in the ENSDF file, and some quantities that may be given in ENSDF (lifetimes, for example) do not have any RadWare-format equivalent. For this reason, DO NOT assume that any RadWare-format file gives a true representation of the assignments made (or not made) in ENSDF!


Instructions for getting schemes by manual ftp:

YourComputer> ftp radware.phy.ornl.gov

Login as user ftp, using your e-mail address as a password.
For example:
radware.phy.ornl.gov FTP server ready.
Name: ftp
Guest login ok, send your complete e-mail address as password.
Password: your_email@your.domain
Guest login ok, access restrictions apply.

Then type:

ftp> cd pub/nd/aaa      (where aaa is the three-digit mass number
ftp> dir                  of a nuclide of interest, e.g. 157 or 048)
ftp> ascii
ftp> get filename.txt   (where filename is the name of a file that
ftp> get filename.ags     interests you.  Get as many as you like.)
ftp> quit
