The (7Li,7Be) and (7Li,7Beγ) reactions have been studied at bombarding energies of 50 A MeV on targets of 6Li, 12C, 90Zr, 120Sn, 208Pb, and polystyrene. The detection of Doppler-shifted γ-rays from excited 7Be permits the identification of the spin

A large solid-angle array of Low Pressure Multi-Wire Proportional Counters (LPMWPCs) has been constructed as part of the ATLAS Positron Experiment (APEX). Eight three-element trapezoidal counters span 360° in φ and 20–68° in laboratory θ. Angle

Comparison of Bayesian and classical reconstructions of tomographic gamma scanning for assay of nuclear materials

Autor: D.J. Mercer, T.L. Burr, T.H. Prettyman

Tomographic gamma scanning has been used to assay special nuclear material for the past several years. Field experience suggests that the data analysis techniques can significantly affect the assay uncertainty. For example, a positive bias has been o

The charge exchange reaction (6Li,6 He) has been investigated around 0° at 100 A.MeV on 12 C, 13 C, 58 Ni, 90 Zr and 208Pb targets. Strong selectivity for L = 0, S = 1 states in 12N and 13N nuclei is observed. Due to the finite angular opening of th
