Abstract: The angle-differential cross sections of neutron-induced d production from carbon were measured at neutron energies 33.9 MeV at China Spallation Neutron Source (CSNS) Back-n white neutron source. By employing the ΔE-E telescopes of the Light-charged Particle Detector Array (LPDA) system at 24.5° to 155.5° in the laboratory system, the angle-differential cross sections of the 12C(n,d)x reactions were measured.
The experimental results are in good agreement with the previous ones.The present work can provide a reference to the data library considering the lack of experimental data.

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.
