The hexadecapole transition strength distribution is measured for the deformed nucleus ${}_{}{}^{150}{}_{}{}^{}\mathrm{Nd}$ using the (p,p’) reaction at $E_p$=30 MeV. The experimental information on B(E4) values in this nucleus and in ${}_{}{}^{156}{}_{}{}^{}\mathrm{Gd}$ is interpreted in the framework of the sdg interacting boson model. It is found that the main features of the experimental data are fairly well reproduced by a Hartree-Bose method plus Tamm-Dancoff approximation.
