Journal of Chemical Physics, American Institute of Physics, 2017, 146 (2), pp.024106. ⟨10.1063/1.4973612⟩

International audience; We focus on the long-pending issue of the inadequacy of the Dirac bubble potential model in the description of He–He interactions in the continuum [L. L. Lohr and S. M. Blinder, Int. J. Quantum Chem. 53, 413 (1995)]. We attr

Journal of Chemical Physics, American Institute of Physics, 2015, 142 (8), pp.084302. ⟨10.1063/1.4913212⟩

International audience; Owing in part to the p orbitals of its filled L shell, neon has repeatedly come on stage for its peculiar properties. In the context of collision-induced Raman spectroscopy, in particular, we have shown, in a brief report publ
