Transmission of 235U fission fragments in solid media

Transmission measurements of the fission fragments arising in U²³⁵ thermal-neutron-induced fission were performed in Mg, Al, Fe, and Ag by using a back-to-back fission chamber. From the transmission curves, it is possible to derive the relative atomic stopping powers of the different targets and the ranges of the fission fragments in the elements investigated. The experimental results are compared with the theoretical calculations of Lindhard, Scharff, and Schi\o{}tt concerning the loss of energy of heavy ions in matter.
