The relativistic R-matrix method is used to calculate elastic and inelastic cross sections for electrons incident on caesium atoms with energies from 0-3 eV. In addition to the total cross sections, results are presented on the differential cross sections, sigma , and the spin polarisation, P<sub>y</sub>, of the scattered electrons as a function of energy at the scattering angles 10 degrees , 50 degrees , 90 degrees and 150 degrees . The calculation reveals a wealth of resonances around the <sup>2</sup>P<sub>1/2</sub> and <sup>2</sup>P<sub>3/2</sub> thresholds. The resonances are analysed in detail and their role in the scattering process is discussed.
