Triggering of ¹⁷⁸m²Hf isomer embedded in Ta matrix by 30 keV electrons
¹⁷⁸m²Hf isomer triggering was studied using the upgraded experimental setup developed in Kharkiv National University and installed at Kyiv Institute for Nuclear Research. The target presenting a single Ta foil of 300 μm thickness with ¹⁷⁸m²Hf isomeric activity of about 100 Bq was irradiated by 30 ke...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | ¹⁷⁸m²Hf isomer triggering was studied using the upgraded experimental setup developed in Kharkiv National University and installed at Kyiv Institute for Nuclear Research. The target presenting a single Ta foil of 300 μm thickness with ¹⁷⁸m²Hf isomeric activity of about 100 Bq was irradiated by 30 keV electron beam. The enhanced counting rates of all the ground-state band transitions were observed. Our data are consistent with an estimate for the triggering effect of (2.9 ± 0.7)% and corresponding triggering cross-section can qualitatively be estimated as σtrig = 4.2 × 10-²⁷ cm². |
