High-Resolution RBS

The Rb-81/Kr-81m generator can be used as an example. Experience has shown that a large field of view (LFOV) gamma camera equipped with a high resolution collimator requires the cumulative activities for the three typical procedures summarized in Table II. Solving equation (15) by succesive... [Pg.194]

In the high-resolution ESR (326 GHz) study of the biradical state Qa - Qb - in the Rb. Spheroids, RC determines the exchange integral in the biradical (Jo = 109 s 1) (Calvo et al., 2001). Because the rate constant of electron transfer from Qa to Qb is essentially less (kET 104 s 1) (Feher et al., 1992 Xu et al, 2000) than expected for an nonadiabatic activationless ET and the kET values considerably deviate from the dependence of the supperexchange attenuation parameter (yET) on the distance between donor and acceptor centers in RCs (Fig. XXX), we can conclude that the ET is adiabatic and requires thermal activation. [Pg.124]
