Physical review letters

Wang CX, Kim KJ.
PMID: 12005687
Phys Rev Lett. 2002 May 06;88(18):184801. doi: 10.1103/PhysRevLett.88.184801. Epub 2002 Apr 18.

A linear theory is developed for ionization cooling of muon beams in periodic channels that can provide cooling of the transverse emittances and also of the longitudinal emittance via emittance exchange. The channels incorporate solenoids and quadrupoles for transverse...

High-temperature solution phase reaction of iron(III) acetylacetonate, Fe(acac)(3), with 1,2-hexadecanediol in the presence of oleic acid and oleylamine leads to monodisperse magnetite (Fe(3)O(4)) nanoparticles. Similarly, reaction of Fe(acac)(3) and Co(acac)(2) or Mn(acac)(2) with the same diol results in monodisperse...

The decay psi(2S)-->K(0)(S)K(0)(L) is observed using psi(2S) data collected with the Beijing Spectrometer at the Beijing Electron-Positron Collider; the branching fraction is determined to be B(psi(2S)-->K(0)(S)K(0)(L))=(5.24+/-0.47+/-0.48)x10(-5). Compared with J/psi-->K(0)(S)K(0)(L), the psi(2S) branching fraction is enhanced relative to the prediction...

Study of transport behavior for Fe-doping La(0.67)Ca(0.33)MnO3 perovskite manganese.

Systematic studies of the transport properties of La(0.67)Ca(0.33)Mn(1-x)Fe(x)O3 (x=0-0.3) systems showed that with increasing Fe-doping content x the resistance increases and the insulator-metal transition temperature moves to lower temperature. For small doping content, the transport property satisfies metal transport...
