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.

NuSTRAP Mini-Workshop 06.15

Today was a very very very interesting day for our group. I am particularly happy, we managed to gather in a room, some twenty of us, and go through our first mini-Workshop.
The First NuSTRAP mini-Workshop is a mini one, just because we had only three interesting talks for two hours.

We started at 10 am in a classroom near our lab, had some nice cake and biscuits and coffee, and attended three talks spanning a broad range of subjects, all within the research borders of our group. Ms. Lagaki, a MS student gave a nice overview of ion separation by lasers in ISOLDE, Mr Psaltis followed presenting his talk on p-process nuclei (to be presented in the upcoming p-process Workshop taking place in Cyprus in about 10 days) and Ms Mitsi presented her work on a new analysis code of micro-XRF data collected from ANKA synchrotron facility.

The real profit out of this mini-Workshop is that the whole group gathered together and people working in completely different scientific regimes (from fundamental science to applications) had the opportunity to interact and get informed of the parallel scientific directions the NuSTRAP group has been dealing with the last couple of years. My feeling is that the whole thing was quite successful and deserves to be repeated. September is a very convenient month to do it. I will keep you posted.

Βραβεία Ακαδημίας Αθηνών – Ματιά στα δεδομένα

Τα βραβεία της Ακαδημίας Αθηνών ανακοινώθηκαν πριν περίπου ένα μήνα. Μπορεί κάποιος να τα βρει εδώ.

Με λίγη έρευνα, είναι εύκολο να δούμε ενδιαφέροντα στοιχεία για την ποιότητα των εργασιών, στηριζόμενοι σε στατιστικά στοιχεία που παραθέτουν τα ίδια περιοδικά για την απήχησή τους. Δυστυχώς, η Ακαδημία Αθηνών δε δημοσιεύει όλες τις εργασίας που έχουν κατατεθεί ανά κατηγορία διαγωνισμού, ώστε να είναι εύκολη και η σύγκριση με τις βραβευμένες.

Να σημειωθεί ότι στο PDF που παραθέτω περιλαμβάνονται στοιχεία μόνο για έγκριτες δημοσιεύσεις (έχουν παραληφθεί βιβλία, μελέτες σε ειδικά έντυπα και υποτροφίες).

Τα σχόλια και συμπεράσματα δικά σας.
