METHOD     (EDE,PHD)                                              2232200100008 
DETECTOR   (IOCH)  A twin frisch gridded ionization chamber was   2232200100009 
            used. The distance cathode - grid was 46 mm and the   2232200100010 
            distance grid - anode was 12 mm. These dimensions were2232200100011 
            adapted in view of a working pressure of 0.6E+05 Pa.  2232200100012 
            Both CH4 gas and a mixture of 90% argon and           2232200100013 
            10% CH4 were used as counter gases, with N55          2232200100014 
            quality at pressures of 0.6E+05 Pa and 1.2E+05 Pa. At 2232200100015 
            the lower pressure no absolute calibration using alpha2232200100016 
            particles from Cf-252 could be performed. The voltages2232200100017 
            applied to the chamber plates were -2.5 kV on the     2232200100018 
            cathode and +2.1 kv on the anode for both counter     2232200100019 
            gases at 0.6E+05 Pa. For the 1.2E+05 Pa pressure the  2232200100020 
            voltages were -2.5 kV on the cathode and +2.1 kV on   2232200100021 
            the anode for the gas mixture, and -2.5 kV on the     2232200100022 
            cathode and +2.1 kV on the anode and -4.7 kV on the   2232200100023 
            cathode and +4.0 kV on the anode for CH4.             2232200100024

SAMPLE     .The Cf-252 sample was mounted on a 0.12 mg/cm2 nickel 2232200100026 
            backing in the center of the common cathode.          2232200100027 
CORRECTION .The data were corrected for electronic instabilities  2232200100028 
            and different calibration factors between the four    2232200100029 
            electronic chains. The frisch grid inefficiency was   2232200100030 
            also taken into account. The angle-dependent energy   2232200100031 
            loss in the sample and backing was experimentally     2232200100032 
            determined and incorporated in the analysis. Mass     2232200100033 
            dependent corrections for the pulse height defect,    2232200100034 
            PHD, were applied.                                    2232200100035

COMMENT    .This is an investigation of how the determined        2232200100037 
            quantities depend on the choice of counting gas. It   2232200100038 
            was found that the mixture 90% argon and              2232200100039 
            10% CH4 gave the most reliable results.               2232200100040
