|Abstract:||In connection with the Casimir eﬀect for a spinor ﬁeld in the presence of an external magnetic ﬁeld, of special interest are solutions of the Dirac equation in the domains restricted by two planes, which have vanishing the third projection of the conserved current Jz on two boundaries. General conditions for vanishing the current are formulated, they are reduced to a linear homogeneous algebraic system, for which solutions exist when vanishing the determinant of the linear system, that is for the roots of a 4-th order algebraic equation with respect to the variable e2ika, where a is a half-distance between the planes, and k stands for the third projection of the Dirac particle momentum. All solutions of the equation have been found explicitly, each of them provides us in principle with a special possibility to get the quantization rules for parameter k; the most of produced expression for the roots can be found with respect to parameter k only numerically. Generally, solutions depend on 4 arbitrary phase parameters which inﬂuence the appropriate wave functions with vanishing current: Jz(z = −z, +a) = 0.|
