  We present spectroscopic and photometric analysis for eight field galaxies in
the direction of the galaxy cluster LCDCS-S001. The spectra were obtained with
the GMOS instrument in the Gemini South Observatory. The objects were selected
in an i' band image and the multi-object spectroscopic observations were
centered at 7500 A. For the galaxies ID 440 and ID 461 we have determined
redshifts of z=0.7464 and z=0.7465, respectively. For the other six galaxies we
have confirmed the redshift calculated by Rembold & Pastoriza (2006). The
redshifts of the field galaxies are in the range of 0.2201 < z < 0.7784. We
determined the blue and visual luminosities and they are brighter than
M_B=-18.64. The galaxies ID 180, ID 266, ID 461 follow the Faber-Jackson
relation of the Coma and Virgo early-type galaxies, and therefore do not
present a brightening of the B luminosity as observed in galaxies at higher
redshifts. The stellar velocity dispersion was measured for five galaxies and
estimated to be in the range of 200 < sigma < 346 km/s. Lick indices were
measured and used to determine the stellar population properties of galaxies ID
120 and ID 146, by means of spectral synthesis. The first galaxy, ID 120,
presents in its spectrum absorption and emission lines, and we have found that
the main contribution in the flux at lambda 5870 A is of a 0.1 Gyr stellar
population of solar metallicity. For ID 146, the dominant flux contribution at
lambda 4200 A, is provided by a stellar population of 10 Gyr of subsolar
metallicity. From stellar population synthesis we estimated reddening values of
E(B-V)=0.90 and E(B-V)=0.82 for ID 120 and ID 146, respectively. According to
classical diagnostic diagrams the emission lines present in the spectrum of ID
120 indicate that it is a starburst galaxy.
