Measurement and analysis of the isomeric cross section ratios for the ⁹⁴Tc nucleus

NUCLEAR REACTIONS ⁸⁹Y(⁹Be, ⁹Be), (⁹Be, 4n)⁹⁴Tc/^94mTc, E=45.9, 47.0, 48.1, 49.1, 50.1 MeV; measured ⁹Be scattered particles, off-line γ radiation, Eγ, Iγ using five HPGe detectors at the Heavy Ion Research facility in Lanzhou; deduced σ(E) for the formation of ⁹⁴Tc g.s. and isomers, isomer ratios, fusion σ(E). Comparison with theoretical calculations using PLATYPUS model for the role of complete fusion (CF) following breakup, and with potential model calculation for the role of direct CF without breakup.

RADIOACTIVITY ^94,94mTc(β⁺), (EC)[from ⁸⁹Y(⁹Be, 4n), E=45.9, 47.0, 48.1, 49.1, 50.1 MeV; measured yields, isomeric ratios, Eγ, Iγ, half-lives of decays of ⁹⁴Tc g.s. and ^94mTc from γ-decay curves.
