ResumoThe exotic decay process of $\ensuremath{\beta}$-delayed fission ($\ensuremath{\beta}\mathrm{DF}$) has been studied in the neutron-deficient isotope $^{230}\mathrm{Am}$. The $^{230}\mathrm{Am}$ nuclei were produced in the complete fusion reaction $^{207}\mathrm{Pb}(^{27}\mathrm{Al},4n)^{230}\mathrm{Am}$ and separated by using the GARIS gas-filled recoil ion separator. A lower limit for the $\ensuremath{\beta}\mathrm{DF}$ probability ${P}_{\ensuremath{\beta}\text{DF}}(^{230}\mathrm{Am})>0.30$ was deduced, which so far is the highest value among all known $\ensuremath{\beta}\mathrm{DF}$ nuclei. The systematics of $\ensuremath{\beta}\mathrm{DF}$ in the region of $^{230}\mathrm{Am}$ will be discussed.
