EPJ A Highlight - Analysing Coulomb-excitation experiments with exotic beams

Dedicated detection arrays for particle--ray coincidences are now routinely in use at radioactive-ion beam facilities around the world.

This paper presents a number of novel and alternative analysis techniques to extract transition strengths and quadrupole moments from Coulomb excitation data with Radioactive Ion Beams (RIBs) using the GOSIA code. It is anticipated that related approaches and techniques will gain an even greater importance as a wider range of post-accelerated RIBs becomes available at the next generation of ISOL facilities.

Indeed, recent advances in RIB technology, in particular the increasing range of species and post-acceleration energies available from ISOL facilities, have led to a resurgence of the use of nuclear reactions to study the structure of nuclei. Specifically, Coulomb excitation at safe energies, where the surfaces of the colliding nuclei are kept apart (typically 2-5 MeV/A), is now giving unrivalled information on the electromagnetic properties of exotic nuclei, leading to knowledge of the nuclear shape or, more precisely, the charge distribution of individual states. The usefulness of the technique to extract key nuclear-structure information has been demonstrated since the 1960's with stable beam and target combinations.

The paper addresses the situation where new challenges present themselves when studying exotic nuclei, including dealing with low statistics or number of data points, absolute and relative normalization of the measured cross sections and a lack of complementary experimental data, such as excited-state lifetimes, mixing and branching ratios.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
