Detection of fragments arising from >10 GeV electron-nucleus collisions
Much is understood about the interaction of both high energy electrons with nucleons and lower energy electrons with nucleons and nuclei. Although a number of experiments involving high energy inelastic scattering of electrons from quarks bound in nuclei have been performed, many interpretations of the data are still discussed. A project called PEGASYS was conceived at PEP to further investigate this physics. Unfortunately, the termination of PEP operations curtailed this experiment and much of the physics remains unexplored. In this paper we present some details of one proposed part of this project (tagged nuclear structure functions) and some considerations made in designing a detector suitable for observing very low momentum nuclear fragements around a cold-cluster gas target
Fine structure of the Gamow-Teller resonance revealed in the decay of Ho-150 2(-) isomer
The γ rays following the 72s 150Ho 2- Gamow-Teller β decay have been investigated with the CLUSTER CUBE setup, an array of six EUROBALL CLUSTER Ge detectors in close cubic geometry, providing a γ ray detection sensitivity of 2×10-5 per β-parent decay for γ-ray energies up to 5 MeV. The fine structure of the Gamow-Teller resonance at 4.4-MeV excitation in 150Dy has been studied. The resolved levels are compared with Shell Model predictions
