[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. You can download and use these files directly in gls, escl8r, levit8r, dixie_gls etc. Some more specific details on how to download level scheme files are given below, or you can go directly to the level scheme directory.

Most of the level schemes here are converted from the Evaluated Nuclear Structure Data File (ENSDF) and Experimental Unevaluated Nuclear Data List (XUNDL). There are also some schemes contributed by generous physicists from their own analysis using escl8r etc.

The level scheme directory and level scheme JPEG/PDF view script on this site will let you create figures from the level scheme database directly, without running the RadWare programs yourself. You can zoom and pan the figures, but of course to edit the level schemes you will still need to download the data and run the RadWare software.

The ENSDF level schemes on this site were converted using a modified version of the program FCONV, written by Peter Ekstrom (Lund University, Sweden) and Richard B Firestone (LBL). My version of the code is not ready for general release, but you if you want to get a copy, send me an e-mail.

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!

Downloading RadWare Level Schemes

You can view and/or get these level schemes most easily through the level scheme directory script, but also by pointing your browser at https://radware.phy.ornl.gov/ftp/nd/.

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:


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.
