A critical update of the nuclear EM moments database

Some of you know about my efforts to put together a database containing experimental data of nuclear electromagnetic (EM) moments. I am not going to go into details about what a nuclear moments is; all Nuclear Physics textbooks have extended information on them and why they are useful for nuclear structure.

 I have to clarify that I have stood on the shoulders of giants: Several researchers have tabulated experimental data, both on magnetic dipole and electric quadrupole moments, and made them available in print. Already since my PhD years I found myself struggling to find the proper info out of printed copies of those compilations (PDF were very scarce 10-15 years ago). The most recent compilation has been made available by Nick Stone, a colossal work indeed. Still, printed matter is all you can get.

In 2007 I decided I should take over the very hard task to import the existing compilations into a modern database scheme, check the data and update them frequently, as more and more papers were published. With the help of two students, Kostas Stamou and Thanasis Psaltis, both pursuing doctoral studies as we speak, I managed to have a first version in 2009. Lots of things had still to be done from that point. Frequent updates are considered THE top and most important priority in the philosophy behind the database.

Yesterday, I have completed a major update, past due already from July, however, this one was accompanied by a vast cleanup of citation data, references and errors in all kind of things. The database has currently 5352 entries for 1205 isotopes and each single one of them has been checked for integrity. Nevertheless, I can not really brag about this, as experience has shown me in the past that there is always a good experimental error associated to such works. So, please judge me lightly if you spot something missing. And PLEASE LET ME KNOW.

The database can be found here:


Version is dated: 10.09.2015 and includes all data up to Feb 2014.

I hope you find it useful.
