A New Manuscript of the “Récits D'un Ménestrel de Reims”

Abstract

The charming collection of legends, anecdotes and fables known as the Récits d'un ménestrel de Reims is one of the gems of Old French literature,comparable,in its naïveté and grace, to the prose parts of Aucassin et Nicolette. It has been published three times under different names. The latest, and the only critical edition is that by N. de Wailly, entitled Récits d'un m. mestrel de Reims au treizième siècle.

Calculations of recombination rates for coldHe4atoms from atom-dimer phase shifts and determination of universal scaling functions

“…First, range effects are small here since r/a 2 for 4 He atom-atom scattering (a 2 and r are the two atom scattering length, respectively, in the effective range expansion of p cot δ) is roughly 0.75 nm / 10 nm. Also, the FF calculations include, by construction, certain of the finite range effects to all orders [35]. Figure 2 shows the present phase shifts lie consistently below those of Roudnev but are in good agreement with the calculations of Motovilov et al All our calculated phase shifts (except for ET-ERE LO) are indistinguishable from those of Platter and Phillips [18].…”

“…For the ET-ERE calculations at NLO and NNLO, our values depart from those of Platter and Phillips [18] only at the level of +0.27 and -0.14 %, respectively. Based on the small value of r/a 2 ≃ 0.075, we expect the ET-ERE calculations to converge rapidly, an expectation which is readily confirmed by examination of Table III assertion made above that the FF calculations include some range effects to all orders [35]. Table III also makes it clear that there are significant differences between the HFD-B3-FCII and HFD-B atom-atom potentials on the one hand and the LM2M2 and TTY potentials on the other.…”

“…Moreover, the NLO and NNLO ET-ERE results agree well with the FF phase shifts. As will be discussed in a future publication [35], this behavior is readily explained. First, range effects are small here since r/a 2 for 4 He atom-atom scattering (a 2 and r are the two atom scattering length, respectively, in the effective range expansion of p cot δ) is roughly 0.75 nm / 10 nm.…”

“…where β and C are fixed by the low energy atom-atom phase shifts [35]. We compute these phase shifts directly from the atom-atom potentials along with the corresponding dimer binding energies.…”

“…Now, however, H 0 is independent of the momentum cutoff. A thorough discussion of form-factor calculations like these will be presented in a future publication [35]. Values of B…”
