Query: LiBC - A prevented superconductor   We have investigated the lattice dynamics of LiBC. Experimental Raman and
inelastic neutron scattering results are confronted with density functional
calculations. The excellent agreement between experiment and theory indicates
that we have attained a high level of understanding for LiBC, which by its
structure is closely related to superconducting MgB2 We will show that
annealing of the sample is insufficient to cause Li deficiency and thus produce
the expected superconductivity.
