In this contribution, further evidence of the importance of multiphonon-octupole excitations to describe experimental data in the rare earths and actinides will be presented. First, new results of a (p, t) experiment at the Q3D magnetic spectrograph in Munich will be discussed, which was performed to selectively excite J = 0 states in 240Pu. spd f interacting boson model (IBM) calculations sugg...

The analytical potential of a weak-base macroreticular anion-exchange resin for the quantitative separation of metal ions in thiocyanate media is investigated and demonstrated. Distribution data are given for the sorption of some 25 metal ions from aqueous mixtures of potassium thiocyanate (1.0M or less) and 0.5M hydrochloric acid. The magnitude of the distribution data suggests many possible s...

This paper reviews the current knowledge on rare earths (REs) implanted into GaN with a special focus on their lattice location and on the optical activation by means of thermal annealing. While emission channeling experiments have given information on the lattice location of rare earths following low-dose (≈10 cm) implantation, both in the asimplanted state and after annealing up to 900°C, the...

The orbit measurement and correction system of the LNLS synchrotron light source is presented. Recent changes to the system including the addition of 12 vertical correctors and the use of 16 bit DACs to control the corrector magnet power supplies have improved the vertical orbit repeatability from fill to fill from ±70 μm to ±3 μm. The improved resolution also allowed the implementation of auto...

The Advanced Photon Source uses two distinct control programs for orbit control and stability—a full-featured workstation-based program for orbit control (sddscontrollaw) and an EPICS-based system, the RealTime Fast Feedback System (RTFS), to reduce orbit motion. The sddscontrollaw program has been ported to EPICS and moved from the UNIX environment to an EPICS IOC attached to the RTFS. This EP...

The proposed Transiting Exoplanet Survey Satellite (TESS) will survey the entire sky to locate the nearest and brightest transiting extrasolar planets with orbital periods up to about 36 days. Here we estimate the number and kind of astrophysical false positives that TESS will report, along with the number of extrasolar planets. These estimates are then used to size the groundbased follow-up ob...
