Electron-impact emission cross-sections of Kr were measured from the threshold to 1000 eV for the 5p --> 5s transition in visible to near infrared regions and for the 5s --> 4p resonance lines (116.49 and 123.58 nm) in the VUV region. The experiment was carried out at sufficiently low target pressure to ensure a single collision between an electron and an atom since previously published works show rather large scattering not only in the magnitude, but also in the energy dependence of emission cross-sections, probably because of high target pressures. Absolute emission cross-sections for resonance lines were obtained by normalizing relative cross-sections at effectively zero target pressure to that of hydrogen Lyman-alpha produced in electron impact of H-2. Level excitation cross-sections of the 1s(2) and 1s(4) states (Paschen notation) were obtained by subtracting the total cascade 5p --> 5s cross-sections from corresponding emission cross-sections of the 116.49 and 123.58 nm resonance lines. Obtained results are compared with other experimental and theoretical data.
