摘要	Characterization of Fermi surface of the BaSn(3)superconductor (T-c similar to 4.4 K) by de Haas-van Alphen (dHvA) effect measurement reveals its non-trivial topological properties. Analysis of non-zero Berry phase is supported by theab initiocalculations, which reveals a type-II Dirac point setting and tilting along the high symmetricK-Hline of the Brillouin zone, about 0.13 eV above the Fermi level, and other two type-I Dirac points on the high symmetric Gamma-Adirection, but slightly far below the Fermi level. The results demonstrate BaSn(3)as an excellent example hosting multiple Dirac fermions and an outstanding platform for studying the interplay between nontrivial topological states and superconductivity.
