Results of proton and electron inelastic scattering suggest that the interpretation of the 5{sub 1}{sup {minus}}-7{sub 1}{sup {minus}}-9{sub 1}{sup {minus}} sequence in {sup 144}Nd as simple quadrupole-octupole-coupled states neglects large {nu}({ital f}{sub 7/2}{ital i}{sub 13/2}){sub 5,7,9} components and, therefore, that the interpretation of the 12{sup +} state at 4354 keV as a double-octupole-phonon state (6{sub 1}{sup +}{circle_times}octupole{circle_times}octupole) given by Bargioni {ital et} {ital al}. [Phys. Rev. C {bold 51}, R1057 (1995)] may be too simple. It is suggested that measurements of the 9{sub 1}{sup {minus}} state via single-neutron-stripping reactions and intermediate energy proton scattering can help determine the underlying structure of the 4354 keV state. {copyright} {ital 1996 The American Physical Society.}
