Surrogate neutron-capture studies with fission detection in inverse kinematics at the ESR storage ring
Bogusław Włoch, Camille Berthelot, Guy Leckenby +39
The NECTAR (Nuclear rEaCTions At storage Rings) experiment at the ESR heavy-ion storage ring at GSI/FAIR Darmstadt is dedicated to surrogate reaction studies of neutron-induced rea…
Half-life determination of heavy ions in a storage ring considering feeding and depleting background processes
R. J. Chen, G. Leckenby, R. S. Sidhu +49
Heavy-ion storage rings have relatively large momentum acceptance which allows for multiple ion species to circulate at the same time. This needs to be considered in radioactive de…

G. Leckenby, M. Trassinelli, R. J. Chen +47
The measurement of the bound-state decay of at the Experimental Storage Ring at GSI, Darmstadt, has recently been reported with substantial impact on…
Testing strong-field QED to second-order in the highly correlated atomic system berylliumlike Pb78+ by electron-ion recombination spectroscopy
S. Schippers, C. Brandau, S. Fuchs +33
A low-energy storage ring with an ultracold electron cooler has been coupled with a heavy-ion accelerator facilitating high-resolution electron-ion collision spectroscopy of the he…
A Setup to Study Atomic State Population Dynamics and Optical Polarization at CRYRING@ESR
K. Mohr, R. Sánchez, W. Nörtershäuser +26
We present a recently established setup for laser spectroscopy at CRYRING@ESR at the GSI Helmholtz Centre for Heavy Ion Research. Here, laser spectroscopy can be performed on store…
First simultaneous measurement of the gamma-ray and neutron emission probabilities in inverse kinematics at a heavy-ion storage ring
M. Sguazzin, B. Jurado, J. Pibernat +50
The probabilities for gamma-ray and particle emission as a function of the excitation energy of a decaying nucleus are valuable observables for constraining the ingredients of the…
Measurement of the Isolated Nuclear Two-Photon Decay in
D. Freire-Fernández, W. Korten, R. J. Chen +57
The nuclear two-photon or double-gamma () decay is a second-order electromagnetic process whereby a nucleus in an excited state emits two gamma rays simultaneously. To be able…
First measurement of the neutron-emission probability with a surrogate reaction in inverse kinematics at a heavy-ion storage ring
M. Sguazzin, B. Jurado, J. Pibernat +50
Neutron-induced reaction cross sections of short-lived nuclei are imperative to understand the origin of heavy elements in stellar nucleosynthesis and for societal applications, bu…
Storage, Accumulation and Deceleration of Secondary Beams for Nuclear Astrophysics
J. Glorius, Yu. A. Litvinov, M. Aliotta +61
Low-energy investigations on rare ion beams are often limited by the available intensity and purity of the ion species in focus. Here, we present the first application of a techniq…
Determination of luminosity for in-ring reactions: A new approach for the low-energy domain
Y. M. Xing, J. Glorius, L. Varga +59
Luminosity is a measure of the colliding frequency between beam and target and it is a crucial parameter for the measurement of absolute values, such as reaction cross sections. In…
