Free MössWinn Training Course

Dear colleagues, hello everyone!

Thank you for your long-term support to the Mössbauer Effect Data Center. In recent years, we have had the privilege of working with Dr. Zoltán Klencsár and developed a brand new Mössbauer database system and added some new features to the database. The development of the new features of our database still is continuing, please continue to pay attention to and support.

This email is to give you a completely free MössWinn spectrum fitting software ( training information, by Dr. Zoltán Klencsár in English and MEDC's staff Dr. Rile Ge in Chinese with a combination of online and on site styles, interested colleagues welcome to arrange time to sign up, or arrange your team posdocs, doctoral students, master students and young scholars to sign up. The attachment is the registration form, the deadline is Nov. 22th, 2022. For enquiry about this training course, please email to:

Introduction to Mössbauer spectrometer  & MossWinn

Dr. Zoltán Klencsár

Nov. 25th, 2022


Mössbauer spectroscopy technique & Fitting & Database

Dr. Rile Ge

As we know, Dr. Zoltán Klencsár is the developer of MössWinn spectrum fitting software, and his lectures mainly may include these aspects:

- Introduction to the main Mössbauer spectrometer setups (transmission, reflection)

- Introduction to the hyperfine interactions (hyperfine magnetic interaction, quadrupole interaction, isomer shift) and to their appearance in the Mössbauer spectrum.

- Explanation of unfolded spectra and the folding and reversal procedures.

- Introduction of topics related to the calibration of the velocity axis.

- Introduction of MössWinn's data formats and special data formats.

- Introduction of MössWinn's project system, and the meaning of red, green, blue and gray framed windows.

- Introduction of the FIT menu capabilities: setting up a model in the FIT menu (large topic, among others including distributions and the MIDB)

- Evaluation functions of the fit (chi-square, sum of squares, absolute deviation)

- Introduction of the FIT menu capabilities: calibration of the velocity axis via fitting in the FIT menu.

- Introduction of the FIT menu capabilities: fitting a single calibrated spectrum (local tuning, global search)

- Calculation of the standard error of fit parameters.

- Simultaneous fitting of several spectra, exporting the results from the FIT menu.

- Application of external DLL libraries.

- Transmission integral.

- Some further examples.

Some of the above would be on pptx slides others he would present live in MössWinn. The audience would have a demo version of MössWinn in which the steps he present could be made on their own computer, but through the internet he could not do a practice-like lecture where he help the audience to carry out the same steps that he am presenting.

The lecture of Dr. Rile Ge would focus more on the practical aspects by letting the audience do actual calibrations and spectrum fittings and how to use the MEDC database, as she could help the audience more efficiently on the site.
