We consider the transmission of classical information over a quantum channel. The channel is deened by an \alphabet" of quantum states, e.g. certain photon polarizations, together with a speciied set of probabilities with which these states must be sent. The Levitin-Kholevo theorem implies that the amount of information transmitted per \letter" cannot be(More)
A shell of neutron detectors was designed, constructed, and employed in γ−ray spectroscopy with Gammasphere. It consists of up to 35 tapered regular hexagons that replace the same number of forward Ge-detector modules in Gammasphere. The shell was designed for high detection efficiency and very good neutron−γ discrimination. The simultaneous use of time of(More)
Five prompt proton decay lines have been identified between deformed states in (59)Cu and three spherical states in (58)Ni by means of high-resolution in-beam particle-gamma gamma coincidence spectroscopy. The GAMMASPHERE array coupled to dedicated ancillary detectors including four Delta E-E silicon strip detectors was used to study high-spin states in(More)
The ground state rotational bands of the N = Z nuclei (72)Kr, (76)Sr, and (80)Zr have been extended into the angular momentum region where rotation alignment of particles is normally expected. By measuring the moments of inertia of these bands we have observed a consistent increase in the rotational frequency required to start pair breaking, when compared(More)
