    Abstract

    178m2Hf is an extremely interesting isomeric state due to its potential energy capacity level. One possible way to obtain it is by irradiation of a natTa sample with a high-current proton accelerator. Up to now, there was no information in the international experimental nuclear data base (EXFOR) for this reaction. Irradiations of natTa samples performed for other purposes provide an opportunity to address this question. This paper presents the 172m2Hf independent production cross-sections determined by gamma-ray spectrometry. The natTa(p,x)172m2Hf excitation function is studied in the 20-3500 MeV energy range. Comparisons with results by several nuclear models (ISABEL, Bertini, INCL4.5+ABLA07, PHITS, CASCADE07, and CEM03.02) used as event-generators in modern transport codes are also reported. However, since such models are generally not able to separately predict ground and isomeric states of reaction products, only 178Hf independent and cumulative cross-section data are compared.
