{pi}{sup +} and {pi}{sup -} elastic and inelastic scattering to the 2{sub 1}{sup +}(4.44 MeV) state on {sup 12}C at 995 MeV/c were measured over an angular range for elastic-scattering from 5.4 deg. to 28.2 deg. and for inelastic scattering from 15.2 deg. to 22.8 deg. Both of the elastic-scattering data sets were well reproduced by first-order factorized momentum-space optical potential calculations with free {pi}-N elementary amplitudes and three different ground state densities, which were deduced from the charge density and microscopic model calculations, the cluster model and the shell model. We also extracted {sigma}{sub tot},{sigma}{sub el}, and {sigma}{sub R} phenomenologically and compared them with a Fermi averaging model. The inelastic cross sections of {pi}{sup +}-{sup 12}C and {pi}{sup -}-{sup 12}C were compared with the DWIA calculations, one using the transition density(0{sup +}{yields}2{sub 1}{sup +}) deduced by the cluster model and the other using the transition density deduced by the shell model.
