Abstract:

We solve the Duffin-Kemmer-Petiau equation in the presence of a pseudoscalar potential step in (1 + 1) dimensions. We show that the paradox of Klein is not found for particles of spin-1, contrary to the case of the particles of spin-0 where it always persists. The absence of this paradox in the vector bosons is explained with the arguments based on effective mass.PACS Nos.: 03.65.Pm; 03.65.Ge

L'équation de Duffin-Kemmer-Petiau est résolue en présence d'un pseudopotentiel échelon en (1 + 1) dimensions. Nous montrons qu'il n'y a pas de paradoxe de Klein dans le cas des particules de spin 1, mais qu'il est présent pour des particules de spin 0. L'absence de ce paradoxe dans le cas des bosons vecteurs s'explique par un argument basé sur la masse effective.
