We employ the coordinate-independent plane wave solution in de Sitter space to study the spin- particle production. The so-called plane waves in the zero-curvature limit reduce to the usual plane waves in flat space. Previously in (Int. J. Mod. Phys. D 24, 1550052 (2015)) we used such modes to study the instability of the de Sitter space, here, by explicit calculation, we study the sipn-
particle creation in de Sitter space caused by mixing modes.
