title = "Electronic and phonon-mediated gap modes in A15 compounds",
abstract = "Results of Raman-scattering experiments on superconducting A15 Nb3Sn and V3Si are reported. Phononic and electronic excitations of all three Raman-active symmetries are investigated as a function of temperature. The origin of the observed gap modes is discussed. The zero-temperature gap energies found by light scattering are 4.7 and 5.4 kBTc for V3Si and Nb3Sn, respectively.",

note = "Funding Information: 5% (Fig. 2,4) in qualitative accordance with theoretical predictions for NbSes. s In conclusion, our experiments reveal some new aspects concerning the origin of the gap modes. The {"}A~{"} bands being of electronic origin exhibit an anisotropy of nearly 10~. The maximum gap energies of 4.7 and 5.4 keTe observed in V~SI and Nb3Sn, respectively, exceed. the values found by other means. The low energy of the E~ gap mode is assumed to originate from the specific scattering mechanism. Financial support by the Deutsche For-schungsgemeischaft and the Bundesforschungs-mlnlsterium is gratefully acknowledged.",
