1124900500003 SAMPLE The calcium sample used in the experiments was 1124900500004 machined out of Ca metal and painted with glyptal 1124900500005 to retard oxidation. Areal density 0.187x10**24 1124900500006 atoms/cm**2. 1124900500007 METHOD (TRN) Cross sections were obtained by measuring the 1124900500008 transmission of the neutrons through a circular disk, 1124900500009 assuming an exponential decrease of neutron intensity 1124900500010 in the sample. 1124900500011 STATUS (CURVE) Fig. 5, page 1126. 1124900500012 (TABLE) Data above 100 keV taken from
