Resonance effects in near-barrier fission observed in (d, pf) reactions

Resonances in the isomeric and prompt fission probabilities of240Pu

“…has been chosen in the present work because of the detailed knowledge of intermediate structure at higher excitation energies from previous investigations [2][3][4] and the convenient isomeric half-life of 4 ns. Following a description of the experimental set-up in Section II the results obtained are presented in Section III.…”

Determination of the primary reactions of photosynthesis from transient ESR signals

“…Moreover, the integrated (or net) polarization of either radical is zero if and only if the two radicals have identical g-factors; the integrated polarization of a radical increases with increasing g-factor difference. For systems without diffusional motion of the radicals, as the one treated here, the polarization depends linearly upon the difference in ESR-resonance fields between the radicals in the specified spin states, see e.g., [5,7,8]. All these dependencies are satisfied by eq.…”

“…When the values of T1 are not different enough to permit the maximum polarized spectra of the radicals to be determined by this approximate procedure, then the complete time dependence of the observed spectrum must be considered, cf. [8].…”

“…The form of the radical spectra S and D may be understood by the following comments (a rigorous proof is given in [8]). The polarization is created in two radicals which are so close that an exchange interaction between them exist.…”

“…There is thus no need to indicate the absolute sign of I (H) on the ordinate axis. The information contained in the phase of the spectrum is discussed in [8].…”
