    "abstract": "The $\\Delta-N$ electromagnetic transition form factors are calculated in the\nPoincar\\\u0027e covariant quark model in three forms of relativistic kinematics.\nAddition of $D-$state components to pure $S-$state model wave functions, chosen\nso as to reproduce the empirical elastic electromagnetic nucleon form factors\nwith single constituent currents, brings the calculated $R_{EM}$ ratio for the\n$\\Delta(1232)\\to N\\gamma$ transition closer to the empirical values in instant\nand point form kinematics. The calculated $R_{SM}$ ratio is insensitive to the\n$D-$state component. In front form kinematics the substantial violation of the\nangular condition for the spin 3/2 resonance transition amplitude in the\nimpulse approximation prevents a unique determination of $R_{EM}$ and $R_{SM}$,\nboth of which are very sensitive to $D-$state components. In no form of\nkinematics do $D-$state deformations of the rest frame baryon wave functions\nalone suffice for a description of the empirical values of these ratios.",
