Abstract:                                ! Free format text (please update)
    We propose to utilize HST data for  quantitative studies that
    will allow a very rigorous examination to be made of the
    evolutionary state of galaxies in intermediate redshift
    clusters. The Fundamental Plane (FP) of early-type galaxies is
    one of the most sensitive tests for galaxy evolution. This is
    because of its low intrinsic scatter for nearby cluster
    galaxies. It can be used to accurately measure the luminosity
    evolution of galaxies, and the change of M/L with time. We
    have started a program to determine internal velocity
    dispersions of galaxies in six rich, X-ray selected clusters
    at redshifts between 0.3-0.6 with the Keck telescope. This
    project is part of the thesis for graduate student, Dan
    Kelson. We propose here to use the high resolution HST data
    from the archive on two X-ray clusters at z=0.31 and z=0.38 to
    determine very accurate scale lengths, surface brightnesses
    and morphologies.  These results will be combined with Keck
    spectroscopic data for an FP analysis. The first Keck data on
    CL2137-23 is already in hand, and A370 is to be studied in an
    already-allocated run in November. Both A370 and CL2137-23 are
    gravitational lensing clusters and have a rich entourage of
    arclets.  While the galaxies are our highest priority, we plan
    to use unassigned slitlets in the Keck slitmasks to determine
    redshifts and spectral characteristics of the arclets.
