Phys. Rev. C 77, 015803 (2008) [12 pages]Investigation of photoneutron reactions close to and above the neutron emission threshold in the rare earth regionReceived 5 September 2007; published 14 January 2008 We have investigated the photoneutron cross section of the isotopes 148,150Nd, 154Sm, and 154,160Gd close to the neutron emission threshold in photoactivation experiments at the superconducting Darmstadt electron linear accelerator S-DALINAC. Naturally composed targets were activated with a high-intensity bremsstrahlung beam at various energies and the reaction yields have been determined by measuring the activity of the produced radioactive isotopes with HPGe detectors. The results are compared to two different statistical model calculations. © 2008 The American Physical Society URL:
