摘要：

Electromagnetic and nuclear excitations of the neutron-rich Oxygen isotopes ranging from A = 17 to A = 22 are studied experimentally in reactions at energies around 600 MeV/u. By measuring the four-momenta of all decay products the excitation energy is determined. From the differential cross sections for electromagnetic excitation, the El-strength distributions can be deduced. For O-18,O-20,O-22, low-lying dipole strength is observed, exhausting about 5% of the energy weighted TRK sum rule for energies up to 5 MeV above the continuum threshold.
