Descrição: An amplitude analysis has been performed for the reactions <math>\pi^+ p \rightarrow(\eta^0,\omega^0)\Delta^{++}\,\ </math> at 16 GeV/c, constraining the relative spin between the target proton and the <math>\Delta^{++}\,\!</math> to be 1. The amplitudes are determined in intervals of t' by a maximum likelihood fit. The quality of the fits is checked by comparing the experimental decay angular distributions of the <math>\eta^0\,\!</math> , <math>\omega^0\,\!</math> and <math>\Delta^{++}\,\!</math> in the Gottfried-Jackson system. The structure observed in the magnitudes and phases of the obtained amplitudes is consistent with, that expected on the basis of currently accepted phenomenological ideas.
