Phase interruption

Line centers of a number of previously unresolved SF transitions in the fundamental Vj band have been observed by Rabinowitz et al. with this Lamb-dip technique. Measurements of the dip width at small saturation levels yielded a determination of the SFe-SFe cross-sections for phase interrupting collisions. [Pg.68]

Gelation of one or both phases interrupts partitioning of water and large size dispersed particles between the phases. This illustrates the nonequUibrium ... [Pg.34]

Mobile phase interrupted. Insufficient flow from pump. —> Check reservoirs, loop, degassing of mobile phase, and compatibility of mobile phase components. [Pg.1657]

Phase interrupting collisions and J changing collisions affect all hyperfine components alike and thus can account for the basic broadening seen for all components- The coupling between the nuclear spin and the... [Pg.203]

Traditionally, the destruction of p collisions is attributed to a loss of coherence of the phasep for different values of n (phase interruption) of the products A (R, t)A (Rj, t). (The traditional theory is described by, among others, Sobel man (1972).) However, an alternative explanation, applicable in the classical regime, is that j ollisions destroy p reducing the overlap of A (R, t) and A2(Rn this, we assume for simplicity that... [Pg.403]

Since the fault is of a transitory nature, the scheme may be applied even on a per-pole basis, allowing the healthy phases to remain intact and the reclosing necessitated only in the affected phase rather than all the phases, thus further enhancing the system s transient stability. However, it would require an independent interrupting mechanism and individual relaying and tripping schemes for each pole. [Pg.559]

The improvized version of a BOCB is achieved through an MOCB by arranging separate and insulated arc chambers to interrupt each phase separately, thus eliminating the element of fusion with the tank wall. [Pg.633]

The voltage developed would thus oscillate around the normal voltage and fall in phase with the fault current to achieve a near-strike free interruption of the interrupting device on a ground fault. [Pg.666]

Since usually the reference electrode is not equipped with a capillary probe (see Fig. 2-3), there is an error in the potential measurement given by Eq. (2-34) in this connection see the data in Section 3.3.1 on IR-free potential measurement. The switching method described there can also be applied in a modified form to potential-controlled protection current devices. Interrupter potentiostats are used that periodically switch off the protection current for short intervals [5]. The switch-off phase is for a few tens of microseconds and the switch-on phase lasts several hundred microseconds. [Pg.448]

The simplest scheme that accounts for the destruction of phase coherence is the so-called stochastic interruption model [Nikitin and Korst 1965 Simonius 1978 Silbey and Harris 1989]. Suppose the process of free tunneling is interrupted by a sequence of collisions separated by time periods vo = to do After each collision the system forgets its initial phase, i.e., the off-diagonal matrix elements of the density matrix p go to zero, resulting in the density matrix p ... [Pg.21]
