performed a direct measurement of self-Kerr nonlinear coefficient in a three-level lambda EIT medium in the presence of
Doppler broadening by using a cavity scanning technique.
These magnetic moments are probably associated with different defects, the plausibility of which is supported by the unique behavior of the S parameter [28] in the depth-resolved
Doppler broadening of PAS measurements of the Al-Co-doped ZnO film explained below.
The topic of his PhD was "The effect of Kerr non-linearity,
Doppler broadening and spontaneous generated coherence on slow light propagation".
(ii) If the line has a predominant
Doppler broadening, which has a Gaussian profile, the real width is given by:
Doppler broadening positron annihilation (DBPAT) provides direct information about core and valance electrons in (CR-39) due to radiation effects.
Investigations into the uptake of water by primers have also been carried out using the positron-based techniques of positron annihilation lifetime spectroscopy (PALS) and
Doppler broadening energy spectroscopy (DBES).
Positron lifetime and
Doppler broadening spectroscopy on opals show a presence of positronium formation.
A much-touted key safety feature of the pebble-bed design lies in the con figuration of the fuel, pebble-bed reactors actually use the U-238 as stopgap "control rod." When core temperatures pass a certain point, causing the uranium atoms in the fuel to vibrate more rapidly, the U-238 atoms offer a wider "profile" to the neutrons zipping around the reactor core--a phenomenon called "
Doppler broadening." As the U-238 absorbs more of the neutrons, the chain reaction slows, shutting down the reactor.
(Unless otherwise noted, all uncertainties given in this paper are standard uncertainties, i.e., one standard deviation estimates.)
Doppler broadening can be avoided if the transition is excited with two counter-propagating photons, as originally proposed by Bender et al.
The cyclic aging is performed on several samples at 26 kV with 8 h of power on and 16 h of power off for aging times of 6, 12 and 18 months and the samples were examined for defect characterization using both
Doppler broadening and positron lifetime techniques.
In particular, the isotope selectivity enhancement can be achieved with the
Doppler broadening reduction, through effective multistep resonance ionization transition [14-16].
Doppler broadening positron annihilation technique (DBPAT) provides direct information about the change of core and valance electrons in Polyallyl diglycol carbonate (CR-39).
