Thermomagnetic hysteresis effects in NiMn and NiNnPd thin films
(AIP Publishing, 2001)
dc magnetization measurements, for zero-field cooled (MZFC) and field-cooled (MFC) cases, have been carried out for flash-evaporated Pd-doped NiMn thin films. These included reentrant phases (Ni76xPdx)Mn24, for 0x5, ...
Asymptotic normalization coefficients and the Be-7(p, gamma)B-8 astrophysical S factor
(American Physical Society, 2001)
We consider the results of two proton transfer reactions, B-10(Be-7, B-8)Be-9 and N-14(Be-7, B-8)C-13, to obtain a weighted average of the measured asymptotic normalization coefficients for the virtual transition 7Be +pB-8. ...
Inversionless lasing with self-generated driving field
(American Physical Society, 2001)
We propose and study resonant ladder schemes of inversionless lasing on a fast-decaying transition when the population inversion is not possible or Very difficult to achieve. The driving field on a neighboring, slowly ...
Measurements and calculations of metastable level lifetimes in Fe X, Fe XI, Fe XII, Fe XIII, and Fe XIV
(American Physical Society, 2001)
Lifetimes of metastable levels in the ground term of Fe ions within the 3s(2)3p(k), k=1-5, isoelectronic sequences have been measured. These measurements were performed utilizing ions that were selected by mass to charge ...
Compensation of ac Stark shifts in optical magnetometry RID B-9041-2008 RID A-1272-2007
(American Physical Society, 2001)
The ac Stark shift of the resonance frequency of the nonlinear magneto-optic effect (NMOE) results in a fundamental broadening of this resonance which limits the precision of optical magnetometry based on NMOE. We have ...
A Visualization of the Global Dynamic Tropopause
(American Meteorological Society, 2001-06-01)
A 20–yr loop of the global tropopause, defined in terms of potential vorticity (PV), is constructed using the NCEP–NCAR reanalysis dataset. This method of visualizing observed upper–tropospheric dynamics is useful for ...
Strangeness equilibration in heavy ion collisions
(American Physical Society, 2001)
Using a relativistic transport model for heavy ion collisions at energies that Lire below the threshold for kaon and antikaon production in nucleon-nucleon collisions, we study how their abundances approach the canonical ...
Spin glass behavior in FeAl2
(American Physical Society, 2001)
Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T-f = 35 K and frequency-dependent susceptibility below T-f. The ...
Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
Fourth-order diffusion Monte Carlo algorithms for solving quantum many-body problems
(American Physical Society, 2001)
By decomposing the important sampled imaginary time Schrodinger evolution operator to fourth order with positive coefficients, we derived a number of distinct fourth-order diffusion Monte Carlo algorithms. These sophisticated ...
