Thin targets of U, Bi, Pb, Au, W, Ho, and Ag were bombarded with 7-GeV protons in order to measure the fission and spallation cross sections. Muscovite mica, Makrofol-N, Makrofol-E, and Daicel track detectors were employed in 4..pi.. and 2..pi.. geometry arrangements. The binary- and ternary-fission cross sections (sigma/sub b/ and sigma/sub t/) and the value of fissility (sigma/sub fission//sigma/sub inelastic/) increase with increasing value of Z/sup 2//A of the target. The spallation cross section (sigma/sub spall/) shows an increase with increasing mass number of the target. However, sigma/sub t//sigma/sub b/ and F/B (forward to backward) ratios decrease with increasing value of Z/sup 2//A.
