abstract:

    line_1:        FOS spectra have been obtained of the Ly-alpha region of 3 quasars
    line_2:        with 21 cm absorption, 3CR 196, PKS 1229-021, and 3CR 286.
    line_3:        The absorbing object is almost certainly a galaxy disk in each case.
    line_4:        Measurement of the damped Ly-alpha line will determine the H I column
    line_5:        density in the 21 cm absorption system, and comparison with 21 cm will
    line_6:        yield the spin temperature. The number of contributing components will
    line_7:        be determined from existing or new 21 cm observations. Comparison with
    line_8:        optical observations will allow the determination of chemical
    line_9:        abundances with respect to H for elements with low-ionization lines.
    line_10:       Images taken after the new WF/PC installation may identify the
    line_11:       absorbing galaxy and, if so, will allow us to characterize the impact
    line_12:       parameter and Hubble type of galaxies producing damped Ly-alpha
    line_13:       absorption at moderate redshift. Two of these will be done in this
    line_14:       proposal.

  question:        3
    section:       1
    line_1:        We will use the WFC with F702W
    line_2:        to image 3CR 196 and PKS1229-021.  1200S per image.

  question:        4
    section:       1
    line_1:        The absorbing objects are lost in the point spread function of the
    line_2:        quasar in ground-based images.

!

  question:        7
    section:       1
    line_1:        These observations will be reduced using the standard imaging
    line_2:        reduction software available for WF/PC data. Calibration
    line_3:        will be done using the results of SV observations.
    line_4:        Already existing software will be used to subtract the image of
    line_5:        the background quasar.

  question:        9
    section:       1
    line_1:        PI has received data from a number of
    line_2:        GTO programs, SAT, and ERO programs.  Related
    line_3:        programs which have had observations are as
    line_4:        follows:
    line_5:        1026 - ``UV Spectra of Low-Redshift-QSOs'': related,
    line_6:        1027 - ``UV Spectra of QSOs with z>  3.1'': not related,
    line_7:        1190 - ``FUV Emission LIne Profiles of W Serpentis
    line_8:        Binaries'': not related
    line_11:       Observations of UM 675 have shown
    line_12:       that any He I Gunn--Peterson effect is small, that
    line_13:       He I absorption lines are not strong, that
    line_14:       predictions of the ``Lyman valley'' may be
    line_15:       correct, and that low redshift Ly-alpha is more
    line_16:       prevalent than expected.  Observations of low
    line_17:       redshift QSOs (including 3C 273) have shown even
    line_18:       more clearly that Ly-alpha absorption occurs in
    line_19:       greater numbers than expected, as well as showing
    line_20:       emission--line profile differences more clearly
    line_21:       than from earlier data.  Unexpectedly, Ly-alpha
    line_22:       is {\it narrower} than H-alpha.

    line_1:        The majority of the resources required for this project other than the
    line_2:        normal facilities of a university (librarys, offices, etc.) were
    line_3:        supplied by NASA to the members of the GHRS IDT for these projects.
