The effect of the breakdown rotational symmetry for the one-body current operador in the null-plane is investigate by comparing calculations within ligth-front and covariant approaches.19 pages include 3 Postscript figures (g0.ps,g1.ps and g2.ps), figures format changed to facilitate downloading, correction name author, use latex,revtex. e-mail: pacheco@axpfep1.if.usp.br and tobias@fis.ita.cta.br, (preprint#IFUSP/P-1241)Nuclear TheoryHigh Energy Physics - Phenomenologytext
