Very neutron-rich fission products of the mass chain A=113 obtained from the IGISOL on-line mass separator have been investigated by coincidence techniques and -spectra multiscaling. Gamma-rays following -decay of 113Tc have been observed for the first time and a new 0.5 s isomeric state has been found in 113Ru.
