Problem 1852

Summary: Mn-54 decay scheme is incorrect in radioactivedecay version 4.3 : no beta minus branch

Description Gilles Grégoire 2016-04-05 14:24:27 CEST 
We use the radioactive decay module for HpGe detector calibration.

We compare with experimental values obtained with radioactive standards including Mn-54, Sn-113, Co-60, Sr-85, Am-241, Cs-137, Cr-51, Ce-139, Y-88, Zn-65, Cr-51

The decay scheme of Mn-54 has been changed from radioactive decay database v4.2 to v4.3 (same in 4.3.1)

The beta-minus way has been changed for something negligible to 100 in file z25.a54 (line 9) so half of Mn-54 decays to Fe-54 (wrong!)

We will check data consistency for other measured nuclides.

Best regards,

Gilles Gregoire

Thank you for this report.  We confirm the bug and will begin the fix.

We appreciate hearing of any further discrepancies you may find.

Dear Mr. Gregoire,

We want to inform you  the data for Mn-54 will be corrected with the new release g4.10.3


Best regards
