Measurement of the g factor of the 4 1 + state in Ge 70

The g factors of the 2 + 1 , 3 - 1 , and 4 + 1 states of 70 Ge have been measured by the transient field technique. The measured value, g(4 + 1 ) = +0.5(2) is in good agreement with the results of shell-model calculations within the full fp configuration space and with the nuclear g-factor systematics in this region. The measured g(4 + 1 ) is consistent with the recently reported positive g(4 + 1 ) value for 68 Zn, the N = 38 isotone of 70 Ge. The determination of the logarithmic slope of the particle-y angular correlations is discussed for two typical arrangements of transient field experiments.
