We have implemented a 47r BaF2 detector system at the Oak Ridge Electron Linear Accelerator (ORELA) for making (n,7) measurements of interest to nuclear astrophysics. This new detector will allow us to work with smaller samples and to avoid potential problems with the pulse-height weighting technique used in other systems. Also, our first measurements with this system demonstrate that as a result of the excellent time-of-flight (TOF) resolution at ORELA and the good pulse-height resolution of the detector, the background from sample-scattered neutrons will not be a serious problem in most cases.

We have completed measurements of the 142'144Nd(n,7) cross sections from approximately 20 eV to 200 keV at the Oak Ridge Electron Linear Accelerator (ORELA) using a recently improved C6D~ detector apparatus. 142Nd is an s-only isotope, i.e. it is only formed during the s-process. It has a closed neu
An independent approach for the measurement of the 12 C(α, γ) 16 O cross section at low energies has been performed at Forschungszentrum Karlsruhe using the 4π BaF 2 detector and the pulsed 3.7 MV Van de Graaff accelerator. Covering the full solid angle, the Karlsruhe 4π BaF 2 detector combines high
We have recently begun a program of high precision measurements of the key production and destruction reactions of important radiochemical diagnostic isotopes, including several isotopes of uranium, plutonium and americium. The detector for advanced neutron capture experiments (DANCE), a 4p BaF 2 ar
The exclusive production of proton-antiproton pairs in the collisions of two quasi-real photons has been studied using data taken at 6 = 183 GeV and 189 GeV with the OPAL detector at LEP. Results are presented for p@ invariant masses, W, in the range 2.15 < W < 3.95GeV. The cross-section measurement
