The conformation and structure of phenyl-alpha-l-fucopyranoside (alpha-PhFuc), phenyl-beta-L-fucopyranoside (beta-PhFuc) and their singly hydrated complexes (alpha,beta-PhFuc.H(2)O) isolated in a molecular beam, have been investigated by means of resonant two photon ionization (R2PI) spectroscopy and ultraviolet and infrared ion-dip spectroscopy. Conformational and structural assignments have b...

This document is an update on TJNAF E-03-109, the Spin Asymmetries on the Nucleon Experiment SANE, conditionally approved in June 2003 by PAC24 for 27 days of beam in Hall C. Our collaboration has been working for the past three years preparing the detector elements, polarized target and auxiliary systems to be ready for installation and data taking in the first half of 2008. SANE is a measurem...

martindale proved that under some conditions every multiplicative isomorphism between two rings is additive. in this paper, we extend this theorem to a larger class of mappings and conclude that every multiplicative $(alpha, beta)-$derivation is additive.

Abstract We report on a hybrid in-beam PET and prompt-gamma Compton imaging system aimed at quasi real-time ion-range verification in proton-therapy treatments. Proof-of-concept experiments were carried out the radiobiology beam line of CNA cyclotron facility using set two synchronous imagers different target materials. The time structure 18 MeV proton was shaped with series beam-on beam-off in...

The $\ensuremath{\beta}$ decay of $^{101,102}\mathrm{Zr}$ and $^{109}\mathrm{Tc}$ was studied using the technique total absorption spectroscopy. experiment performed at National Superconducting Cyclotron Laboratory Summing NaI(Tl) (SuN) detector in first-ever application spectroscopy with a fast beam produced via projectile fragmentation. $\ensuremath{\beta}$-decay feeding intensity Gamow-Telle...

Phononic crystals (PnC) are spatially periodic materials with band gaps that form by Bragg scattering of elastic waves. Within the frequency range a gap, wave propagation is not admitted. A long-standing limitation this class wavelength for band-gap formation must be on order unit-cell size. This restricts presence to relatively high frequencies given lattice spacing. Locally resonant metamater...

Using a macroparticle model for both synchrotron motion and beta-tron motion, we provide formulae for the beam centroid shift, the tune shifts and the growth rates of the longitudinal and transverse head-tail instabilities. Both single turn and multi-turn eeects are included. The transient amplitudes based on the two-particle model are estimated. We estimate the microwave instability for the mu...

 There is growing interest in physics community in building high energy, high luminosity polarized electron-ion collider in order to study the fundamental structure of nucleons and nuclei and details of QCD theory governing the interaction in nuclear matter. eRHIC will take advantage of existing RHIC ion collider at BNL with addition...
