Abstract
The γ-ray spectra resulting from the decay of the 94Tcm,g isomeric pair to the excited states of 94Mo have been investigated using Ge(Li) solid state detectors. Gamma rays (relative intensities are in parentheses) of 871.05(100); 993.19(2.35); 1196.4(0.80); 1522.1 (4.80); 1868.68(6.10); 2393.2(0.50); 2529.8(0.33); 2740.1(3.74); 3129.1(1.47); 3512.5(0.06); 3793.1(0.05); 3892.7(0.016); plus several other weak lines have been observed in the decay of 94Tcm(52 min). Gamma rays (relative intensities are in parentheses) of 449.2(3.3); 532.1(2.35); 702.67(99.7); 742.3(1.21); 849.74(95.8); 871.05(100); 961.10(7.6); 1509.3(0.68); 1592.1(2.25); 1765.6(0.29) have been detected in the decay of 94Tcg(5 h). To investigate this latter activity a hollow coaxial Ge(Li) spectrometer was also used as a well-type detector in order to obtain sum spectra of coincident gamma rays. The overall results obtained from this study allows construction of a level scheme of 94Mo which compares fairly well with previous investigations and removes some inconsistencies shown in Coulomb excitation measurements.Keywords
