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