Inelastic scattering of 162 MeV {pi}{sup {minus}} and {pi}{sup +} was used to study the previously known {ital J}{sup {pi}}=8{sup {minus}} stretched transitions in {sup 60}Ni. A consistent analysis of data from electron and pion scattering to stretched states using both harmonic oscillator and Woods-Saxon wave functions (unbound as necessary) was performed for {sup 60}Ni and three other nuclei: {sup 14}C, {sup 28}Si, and {sup 54}Fe. The experimental pion scattering cross sections were reproduced by distorted-wave impulse approximation calculations using wave functions from ({ital e},{ital e}{prime}) with a normalization factor {ital N} that generally varied from 1 to 5. The ratio of the total isoscalar to the total isovector strength ranged from 0.2 to 1.2. The use of Woods-Saxon wave functions in the analysis did not significantly improve the fits to the angular distributions.
