Query: Recent Calculations of Electromagnetic and Strong Decays of N*   We report on recent calculations of electromagnetic elastic form factors,
helicity amplitudes and strong decay widths of N* resonances. The calculations
are done in a collective constituent model for the nucleon, in which the
resonances are interpreted as rotations and vibrations of an oblate top with a
prescribed distribution of charges and magnetization.
