Abstract Using the high resolution f/96 mode of the FOC we shall image Magellanic Cloud Planetary Nebulae - objects whose diameters are less than 2 arcsec. Their known distances will allow nebular masses to be derived from their angular diameters, yielding the distribution of PN shell masses for the first time. In combination with their nebular expansion velocities, known from ground-based studies, it will be possible to determine the age of the objects. We shall obtain spatially resolved long-slit f/48 spectra of the nebulae to determine the electron density distribution and chemical abundances and to enable detailed nebular modelling thereby yielding the central star effective temperatures and luminosities. Comparison of those two parameters will allow a comparison to be made with the masses derived for the ejected envelopes. ------------------------------------------------------------------------------------ 8.

PROGRAM FOR CYCLE 1 AND SUBSEQUENT CYCLES. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). The aims of this program can only be attained when the majority of targets (i.e., all of priority 1 and 2) are observed. The success of the project depends on deriving the astrophysical properties of the PN group as a whole. Therefore, data should only be released one year after observation of the final priority 2 target. ------------------------------------------------------------------------------------ 12.

We shall carry out high resolution imaging of Magellanic Cloud Planetary Nebulae to determine their masses and ages. Spatially resolved, long-slit UV spectra will yield their electron density distribution and chemical abundances. The nature of the central stars will also be established.
