    "abstract": "Experimental data of the pion charge form factor are well represented by\nPoincar\\\u0027e invariant constituent-quark phenomenology depending on two\nparameters, a confinement scale and an effective constituent--quark mass. Pion\nstates are represented by eigenfunctions of mass and spin operators and of the\nlight-front momenta. An effective current density is generated by the dynamics\nfrom a null-plane impulse current density. A simple shape of the wave function\ndepending only on the confinement scale is sufficient.",
