Major Emphasis

This paper examines those basic theoretical aspects that, in the author's opinion, are relevant for future experimental studies of deuteron photodisintegration, or its time-reversed reaction, at low, intermediate, and high energies. At low photon energies, i.e., [Formula: see text], theoretical aspects stressed by the various authors are contrasted and discussed. At intermediate energies, i.e., [Formula: see text], the major emphasis has to do with the importance of studying the role played by isobars [Δ(1232)], especially in sorting out effects related to substantial energy transfer to the baryonic system. At high energies, i.e., [Formula: see text], the prospect of unraveling manifestations of the quark substructure of hadrons is briefly discussed. For the entire energy region surveyed in this paper, [Formula: see text], it appears essential to measure spin observables so as to disentangle manifestations of the various important aspects relevant for the reaction.

Abstract Unpolarized FTIR and Raman spectra were collected in the regions 4000–4600 cm–1 (NIR) and 100–4000 cm–1 from previously synthesized and characterized amphiboles in the systems richterite–fluoro-richterite, potassic-richterite–potassic-fluoro-richterite, rubidium-richterite–rubidium-fluoro-richterite, and potassic-richterite–deuterated potassic-richterite. The NIR spectra of Na-, K-, and Rb-richterites have peaks at 4325, 4210 cm–1, and 3735–3730 cm–1. All three peaks decrease in intensity with increasing F content, indicating that the higher-energy peaks are combination bands involving the principal OH-stretch at 3735–3730 cm–1 and two OH-libration modes, the frequencies of which can be calculated from the relation ωcombination ≈ ωOH + ωlibration; these are 590 and 475 cm–1, respectively. The FTIR spectra of the richterite–fluoro-richterite and potassic-richterite–potassic-fluoro-richterite series show decreasing intensity and eventual disappearance of the band at ∼600 cm–1 with increasing F in accord with the assignment of this band as due to OH-libration. Raman spectra of the potassic-richterite–deuterated potassic-richterite amphiboles in the low-energy region show the disappearance of two peaks at 585 and 473 cm–1 that we have assigned to OH-libration modes. Collectively, these spectroscopic results indicate that there are two OH-libration modes at ∼590 and ∼475 cm–1 in these synthetic richterites and, by implication, in all monoclinic OH-bearing amphiboles with filled A sites. Similarly to FTIR, the relative intensities of the stretching modes associated with OH-A-OH and OH-A-F local configurations in the Raman spectra provide a reliable estimation of the F content in these A site-filled amphiboles.
