Abstract： Isomer with long lifetime and high excitation energy has great significant in the fields of national strategic security and energy storage. Mastering the method of inducing isomer to decay is the key technology. However, this technology has got into trouble in recent years. For mastering the method of inducing isomer to decay, it is beneficial to start the research on the formation, excitation and de-excitation mechanism of isomer from the view of atomic nucleus structure. In terms of experimental technology, we use the white light neutron beams to bombard Hf target. We established a triple coincidence measurement system, whcih consisted of GTAF-II and HPGE, combined with white light neutron time of flight. Through the analysis of experimental data, we found the sign of the $^{178}$Hf isomeric state exciting to the transition level and releasing rapidly.
