[en] Radioactive ion beams of ¹⁷F were used to study several resonance states in ¹⁸Ne . Clear evidence for simultaneous two-proton emission from the 6.15MeV state (J^π=1^-) in ¹⁸Ne has been observed with the reaction ¹⁷F+¹H . Because of limited angular coverage, the data did not differentiate between the two possible mechanisms of simultaneous decay, diproton (²He ) emission or direct three-body decay. The two-proton partial width was found to be 21±3 eV assuming ²He emission and 57±6 eV assuming three-body decay. The total width of the 1^- state was measured to be 50±5 keV . Several additional resonances that decay by single proton emission were also studied

[en] We have investigated the E1 strength function of ¹¹Be by Coulomb excitation and measurement of the subsequent projectile photon decay. The photons were measured in a wall of BaF₂ detectors. We have used the virtual photon method to extract the photabsorption cross section and hence the dipole strength function. We compare our findings with sum rule predictions. This is a first example of techniques we will extend to heavier mass nuclei

[en] The U.S. Nuclear Science Community in its 1996 Long Range Plan identified an advanced radioactive ion beam (RIB) facility based on the ISOL technique as the next major facility to be constructed for U.S. nuclear physics. The proposed Spallation Neutron Source (SNS) for Oak Ridge National Laboratory, whose construction design funds have recently been appropriated, offers a unique opportunity for the construction of this new facility. Plans for extracting a proton beam from the SNS, transporting it to the RIB facility, and constructing the new RIB facility at the SNS site are discussed, as are the ISOL targets, radiation handling, isobaric separation, acceleration of beams of radioactive ions, and the layout of the experimental areas

[en] The width of the Giant Dipole Resonance in Sn was studied by means of inelastic scattering. This study allowed for the first measurement of the GDR width at a temperature of 1 MeV. The width was found to be 4±1 MeV, and is consistent with the ground state measurement. This result is in disagreement with adiabatic thermal shape fluctuation calculations, indicating an overestimation of the influence of thermal shape fluctuations at low temperature
