Preliminary results of a study of the linear, nonadiabatic, radial-pulsation properties of neutron-star models are presented. Sequences of pure iron models with masses of 1.0 M/sub solar/ and 1.8 M/sub solar/ and a range of luminosities and effective temperatures are considered. Magnetic fields are ignored. The densities of the envelopes at their lower boundary range up to rho approx. 10/sup 12/ g/cm/sup 3/. Equation of state and opacity tables are modifications of those provided by the Los Alamos opacity library (Huebner, et al., 1977). The motivation for this study was to determine whether or not variations of the iron opacity in the outer layers might produce pulsational instability.
