Production of $$^{178}$$Hfm2 and a simple chemical separation method for Hf recovery

Observation of enhanced activity of the 178m2Hf isomeric target after its irradiation by bremsstrahlung radiation

“…At the same time, in the early 2000s, very high-quality and sufficiently strong (∼10 5 Bq) 178m2 Hf isomeric targets were created in the USA, enabling better and faster investigations. Recently, successful attempts to create such isomeric targets have been made in China [30] and Japan [31]. All this inspires a hope that a comprehensive study of the triggering of the 178m2 Hf isomer will not take another quarter of a century.…”
