During the last year the first measurements were obtained of the Hall mobility of electrons injected in an insulating non polar liquid (tetramethyl silane). The resulting Hall mobility appears to be approx. 10% higher than the drift mobility measured on the same sample. We are completing a data acquisition system to be able to correct for several experimental errors that became apparent due, e.g., to the random fluctuations of accelerator current, the nonhomogeneity of the applied electric fields, etc. Theoretical work aimed at the understanding of the observed electric field induced increase of the electron capture rate constant by N/sub 2/O dissolved in Ar and Xe was carried out. Similarly to the conclusions reached in the case of O/sub 2/ and SF/sub 6/ the Stark effect is responsible for the electric field induced changes of the capture probability. Finally a large portion of the equipment necessary for the f.i.r. photoconductivity experiment was constructed. During its testing it became obvious that changes of design were needed because the major source of noise is not expected to be detector noise but instead, shot noise associated with the main electron current.
