Fission fragment mass distributions for 23 nuclei ($$^{234-237}$$U, $$^{236-239}$$Np, $$^{238-241}$$Pu, $$^{240-243}$$Am, $$^{242-245}$$Cm, and $$^{244-246}$$Bk) were measured using the multi-nucleon transfer approach in the reaction of $$^{18}$$O+$$^{237}$$Np, and their excitation-energy dependence was obtained up to a maximum of 70 MeV. Among them, the low energy fission of $$^{236}$$Np, $$^{238}$$Pu, and $$^{245}$$Cm is reported for the first time. The experimental data for all the studied nuclei were compared to the Langevin calculations. The calculation which takes into account the effects of multi-chance fission well reproduced the peak-to-valley ratio and mass-asymmetric peak positions of the distributions. The angular momenta given to the fissioning nucleus is also discussed.
