- Abstract
- The optimal thickness of layers composing nucleus-recoil-sensitive target that enables the measurement of a particular orientation parameter of the final nuclei B-12(gs)(I = 1(+)) and N-16(gs)(I = 2(-)) in the reactions mu(-) + C-12(0(+)) --> upsilon(mu) + B-12(gs)(I = 1(+)) and mu(-) + O-16(0(+)) --> upsilon(mu) + N-16(gs)(I = 2(-)) is estimated according to the current status of art of the slowing down of low energy (recoil energy of B-12 is 376 keV and that of N-16 is 300 keV) charged particles in matter. The choice of materials for orientation preserving (Ni, Ag, Rh) and for orientation-destroying (Al) layers which sandwich the production target layer C or BeO is based on the data obtained with polarized B-12 and N-13 radioactive nuclei beams at the Universite Catholique de Louvain.
