The first identification of the exotic decay process of Electron-Capture Delayed Fission (ECDF) of the very neutron-deficient isotope 234$Bk was performed, and improved ECDF properties for its alpha-decay product 230Am were obtained at the gas-filled recoil separator SHANS2. The isotope 234Bk was produced in the fusion-evaporation reaction 40Ar+197Au->237Bk*->234Bk+3n.

Fusion-fission reactions provide valuable insights into nuclear structure and fission dynamics. They are studied with various techniques, including direct mass and charge measurements and gamma-ray spectroscopy. Prompt gamma-ray emission is commonly used, requiring sophisticated detector arrays and coincidence analysis. We present a complementary spectroscopic method based on medium- and...
