GOLF data continuously obtained over the last two years, provides a unique and ideal set for studying the low frequency (ν <= 500 muHz) range of the solar spectrum oscillations. In this work we have focused our attention to the spectral region around 160 minute (~104.2 muHz), where a controversial ``solar g-mode'' is claimed to be (Kotov et al., 1997). Various spectral techniques have been used in order to reveal its possible presence and stability as well as to set an upper limit to its amplitude. In this poster, the results obtained at the time of the meeting will be presented and discussed.
