mam@ipp.mpg.de: SIMNRA Version 4.0

----------------------------------------------------------------------

From: mam@ipp.mpg.de

Subject: mam@ipp.mpg.de: SIMNRA Version 4.0

SIMNRA version 4.0 has been released. It is available from SigmaBase at
http://ibaserver.physics.isu.edu/sigmabase/ in the programs section.

SIMNRA is a Microsoft Windows 95/Windows NT program with fully graphical 
user interface for the simulation of backscattering spectra for ion beam analysis 
with MeV ions. SIMNRA is mainly intended for the simulation of non-Rutherford 
backscattering, nuclear reaction analysis and elastic recoil detection analysis 
(ERDA) with swift or heavy ions. About 300 different non-Rutherford and nuclear 
reactions cross-sections for incident protons, deuterons, 3He and 4He-ions are 
included.

Version 4.0 has the following improvements:

- - Improved stopping powers for elements: The stopping powers for swift and 
heavy ions now are identical to Ziegler's SRIM 97. The older Andersen-Ziegler 
stopping powers still can be used.
- - Improved fitting algorithm.
- - Different detector energy resolutions for different ions.
- - About 30 new cross-sections for non-Rutherford scattering and nuclear 
reactions have been added, including the bug fix for some proton cross-section 
data files from SigmaBase.

With best regards,
