摘要：
The electromagnetic and axial form factors of the nucleon and its lowest positive parity excitations, the Delta(1232) and the N(1440), are calculated with constituent-quark models that are specified by simple algebraic representations of the mass-operator eigenstates. Instant and front form kinematics demand a spatially extended wave function, whereas in point form kinematics the form factors may be described with a quite compact wave function.
