Grimm [3] demonstrated in ha calculations a wide varistlon m the angular distnbutlon parameter as a function ofchenucal moiety for photolonizatlon above the K shells of oxygen and carbon. Recently, calculations have also been ehtendcd to the effects above the iomzstlon threshold of the K shell of boron m BF, [-I]_ Of particular interest in these calculaltons is the fact that the 0. which for an atomic Is shell of a l Research sponsored by the Dws~on of Chemical Sncnces, Oiiice of BxxEncrgy Sciences.
