G-factors of 2.7 h 93Tc, 4.9 h 94Tc and 20 h 95Tc

Abstract

The hyperfine splitting frequencies gμ N B H.F./ h of 2.7 h 93Tc (J π = 9 2 + ) , 4.9 h 94Tc ( J π = 7 +) and 20 h 95Tc (J π = 9 2 + ) as dilute impurities in Fe have been measured with NMR on oriented nuclei as 336.36(5) MHz, 175.11(1) MHz and 315.97(2) MHz, respectively. From the resonance shifts with an external magnetic field B 0 the hyperfine field of Tc Fe has been determined as -317(5) kG. Taking this into account the nuclear g-factors are deduced as g( 93 Tc) = 1.392(22), g( 94 Tc) = 0.725(11) and g( 95 Tc) = 1.308(21) .
