Coulomb breakup of the neutron-rich isotopes 15C and 17C
Abstract Coulomb breakup of unstable neutron-rich carbon isotopes 15,17 C has been studied at energies around ∼500–600 MeV/nucleon. Non-resonant low-lying dipole strength is observed in theseExpand
Continuum excitations in 6He

Photoneutron cross sections for unstable neutron-rich oxygen isotopes.
The dipole response of stable and unstable neutron-rich oxygen nuclei of masses A = 17 to A = 22 has been investigated experimentally utilizing electromagnetic excitation in heavy-ion collisions atExpand
Direct experimental evidence for strong admixture of different parity states in Li-11
H. Simon,1 D. Aleksandrov,2 T. Aumann,3 L. Axelsson,4 T. Baumann,5 M. J. G. Borge,6 L. V. Chulkov,2 R. Collatz,5 J. Cub,1 W. Dostal,3 B. Eberlein,3 Th. W. Elze,7 H. Emling,5 H. Geissel,5 A.Expand
Two-phonon giant resonances in 136 Xe, 208 Pb, and 238 U
The excitation of the double-phonon giant dipole resonance was observed in heavy projectile nuclei impinging on targets of high nuclear charge with energies of 500‐700 MeV/nucleon. New experimentalExpand
8He–6He: a comparative study of nuclear fragmentation reactions
Dissociation of 227 MeV/u He-8 in a carbon target has been studied in kinematically complete experiments. The data include the relative energy spectrum, angular distributions in the neutron knock-outExpand
Halo excitations in fragmentation of 6He at 240 MeV/u on carbon and lead targets
Dissociation of a 240 MeV/u beam of He-6, incident on carbon and lead targets, has been studied in kinematically complete experiments to investigate low-lying excitation modes in the halo nucleusExpand
Fragmentation of unstable neutron-rich oxygen beams
A. Leistenschneider, T. Aumann, K. Boretzky, L.F. Canto, B.V. Carlson, D. Cortina, U. Datta Pramanik, Th.W. Elze, H. Emling, H. Geissel, A. Grunschlos, K. Helariutta, M. Hellstrom, M.S. Hussein, S.Expand
Large spin alignment of the unbound He-5 fragment after fragmentation of 240 MeV/nucleon He-6
Peripheral fragmentation of a 240 MeV/nucleon beam of the halo nucleus He-6 incident on carbon target has been studied in a kinematically complete experiment. It is found that one-neutron strippingExpand
