The 5th International Workshop on Quasi-Free Scattering with Radioactive-Ion Beams (QFS-RB 2023) will take place at the Porto Galini Seaside Resort & Spa in the beautiful island of Lefkada, Greece, in October 2023 (1st – 6th of October 2023). It is a follow-up
Workshop after Trento (QFS-RB 2008), Azores (QFS-RB 2013), York (QFS-RB 2017) and Maresias (QFS-RB 2019).


The development of new radioactive ion beam facilities providing intermediate to high energy beams (100 MeV/u - 1GeV/u) combined with new experimental setups and techniques allow for kinematically complete measurements with high resolution and efficiency. First
experimental results are now available and many new experimental programs are currently being developed in several experimental facilities including the R3B (Reactions with Relativistic Radioactive Beams) at the FAIR facility at GSI Darmstadt, Germany, as well as
at the RIBF facility at RIKEN, and the FRIB in the US. Among the experimental probes, knockout reactions at quasi-free scattering kinematic conditions in inverse kinematics with hadron targets are used to investigate nuclear properties of unstable short-lived nuclei.
In parallel, in the last decade a wealth of experimental results has been published on short-range correlations using quasi-free scattering reactions with electron probes on stable targets at JLAB in the US. These studies have revealed interesting new phenomena that
could be further enhanced in isospin asymmetric nuclei.

In order to extract reliable information from the experimental data, the interplay between experiment and reaction and structure theories needs to be addressed. From the theory side, one needs a tight control on the reaction formalism, a proper assessment of all excitation mechanisms and a reliable description of all the pair dynamical interactions. In
structure, the role of ab initio versus shell model calculations, non-locality effects, and the role of higher excited states in the continuum must be explored and described.

The Workshop aims to trigger discussions on recent experimental and theoretical results and future plans. An important task is also to illuminate how the physics aspects can be disentangled and to identify the observables and the kinematical conditions allowing to probe
more accurately the dynamical and structural aspects.

To achieve this goal, the Workshop is bringing together theory and experiment experts in the field of quasifree scattering to discuss the latest developments in the field. Following thetradition of past QFS-RB Workshops, it includes experts in short-range correlations to exchange ideas and initiate collaborations.

The topics of the workshop are the following:

• Quasi-free scattering reactions with hadrons and electrons as probes
• Short-range correlations
• Reaction theory
• Spectroscopic factors
• Pair interactions
• Structure effects
• Polarisation observables
• Clustering in nuclei
• Spectroscopy beyond the driplines
• Quasi-free scattering with radioactive ion beams: status and future prospects



The meeting will be held at the Porto Galini Seaside Resort in Lefkada, Greece.


The resort offers a selection of rooms.

Air Travel: The nearest international airport is PVK (Aktion Airport), connecting to many European cities. The airport is 35 km away from the conference site. Athens International Airport is 395 km away from the conference site. You may want to explore Corfu airport as an alternative.
