Update ENDSF file for pyne

[Lorenz Fischer]

Hello,

I have been using the built in nuclear data from pyne 0.7.1 and discovered that some of the isotopes such as Sn128M has an incorrect half life, since it is labeled as 'stable'. 

Does pyne allow the user to change the underlying nuclear data in this case the decay data. Perhaps just update it with the ones from ENDSF? 

I could not find documentation on how one can change/create the nuc_data.h5 file in order have the most up to date values for the isotopes.

Thanks.

Hi Lorenz,

 

Thanks for bringing this to our attention.  We have struggled to keep the ENSDF part of PyNE up-to-date in both the data and processing codes.  Hopefully, we can find someone willing to help out with that.

 

Paul

Hello Paul,

thanks for the quick response.

Is my understanding correct that there is no way to define the ENDSF library yourself, just to have the most up to date data loaded, at the moment?
This means it is basically hard coded for the moment?

Hi Lorenz,

 

That’s not quite correct.  There should be a way to generate your own nuc_data.h5 file from original data, in the same way that we do that. 

 

I’m not sure:

• when we last did that
• who recalls how to do that properly
• if all the ENSDF processing tools will work to do it successfully.
