    Currently, twenty-four calcium, thirty-eight indium, thirty-eight tin and thirty-nine platinum isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the first refereed publication, including the production and identification method, is presented.Comment: to be published in At. Data Nuclear Data Tables, This updated paper combines manuscripts: 1004.4934 (Calcium), 1004.5266 (Indium), 1003.5127 (Tin), and 1006.4033 (Platinum

    Tungsten Film Formation on Silicon by Combining Ionic Decomposition of Metal Halides with Rapid Thermal Processing

    Full text link
    ABSTRACTThin films of tungsten metal and tungsten silicide were formed by combination of spin-on of tungsten chloride dissolved in a volatile organic solvent, decomposition of the chloride by ion bombardment and finally heating in a new versatile Rapid Thermal Processing (RTP) system. The films resulting from this treatment were characterized by Rutherford Backscattering Spectrometry (RBS) prior to and after the ionic decomposition and heat treatment. The procedure and the results of the analysis are described and discussed in terms of process conditions in this paper.</jats:p
