Dependence of the excitation energy, width, and cross section of the isovector monopole resonance

Description: We have used the (..pi../sup -/,..pi../sup 0/) charge-exchange reaction at 165-MeV kinetic energy to study the T + 1 component of the isovector monopole resonance (IVM). The nuclei /sup 40/Ca, /sup 61/Ni, /sup 90/Zr, /sup 120/Sn, /sup 140/Ce, and /sup 208/Pb were used as targets. We also observed the T + 1 component of the giant dipole resonance (GDR) in the lighter targets. The (..pi../sup +/,..pi../sup 0/) reaction also yielded positive results for the T - 1 component of the IVM and GDR in /s… more

Stereo: cylindrical drift chamber for muon decay experiments at LAMPF

Description: A stereo, cylindrical drift chamber has been built for use in a search for rare decay modes of the muon at LAMPF. This chamber (part of the Crystal Box detector) has 728 cells on 8 concentric annuli at alternating angles of 10/sup 0/ to 16/sup 0/ from the chamber axis and with radii from 105 to 220 mm. The basic cell cross section is (9 x 10) mm/sup 2/ and the inter-layer spacing is 4.7 mm. Preliminary results show the single-wire efficiencies to be greater than 99%. Based on results obtained f… more
