Continuous spectra of beta particles and gamma rays emitted in the decay of short-lived fission products in the mass range 98 to 108 have been measured at the on-line isotope-separator LOHENGRIN at ILL. The gamma rays were measured using a NaI(Tl) crystal and the beta particles with a telescope consisting of a {Delta}E-detector in front of a Si detector. The experiment has given beta spectra for the nuclides {sup 98}Zr, {sup 98}Nb, {sup 99m}Nb, {sup 99}Nb, {sup 100}Zr, {sup 100}Nb, {sup 101}Zr, {sup 101}Nb, {sup 101}Mo, {sup 101}{Tc}, {sup 102}Mo, {sup 102}{Tc}, {sup 103}Nb, {sup 103}Mo, {sup 103}{Tc}, {sup 104}Mo, {sup 105}Mo, {sup 105}{Tc}, {sup 106}Nb, {sup 106}Mo, {sup 106}{Tc}, {sup 107}{Tc}, {sup 107}Ru, {sup 108}Mo, {sup 108}{Tc}, {sup 108}Ru, and {sup 108m}Rh. Gamma spectra have been obtained for {sup 98}Y, {sup 98m}Y, {sup 98}Nb, {sup 99}Zr, {sup 99m}Nb, {sup 99}Nb, {sup 100}Zr, {sup 100}Nb, {sup 101}Zr, {sup 101}Nb, {sup 102}Zr, {sup 102m}Nb, {sup 102}Nb, {sup 102m}{Tc}, {sup 102}{Tc}, {sup 103}Nb, {sup 103}Mo, {sup 103}{Tc}, {sup 104}Nb {sup 104}Mo, {sup 104}{Tc}, {sup 105}Mo, {sup 105}{Tc}, {sup 106}Nb, {sup 106}Mo, {sup 106}{Tc}, {sup 107}Mo, {sup 107}{Tc}, {sup 107}Ru, {sup 107}Rh, {sup 108}{Tc}, {sup 108m}Rh and {sup 108}Rh. The experimental gamma spectra are compared with data from the ENSDS file, and the beta spectra with calculated spectra using decay schemes and values from Nuclear Data Sheets (NDS).
