Measurement of the g-factor of the yrast 10+ state in 110Cd

Pushing the limits of excited-state g-factor measurements

“…With a corrected effective hyperfine field a re-analysis of the data from Ref. [37] gives g(10 + ) = −0.29 (16), consistent with that of the expected seniority-two νh 11/2 configuration. A full account of this work has been published [38].…”

“…The consequence is that the effective hyperfine field for the integral perturbed angular distribution measurement of g(10 + ) in 110 Cd was much smaller than adopted in Ref. [37]. With a corrected effective hyperfine field a re-analysis of the data from Ref.…”

“…The hyperfine field of Cd implanted into gadolinium was then investigated. The motivation was to reassess the g-factor measurement on the I π = 10 + state in 110 Cd which reported g(10 + ) = −0.09(3), at least a factor of two smaller than g ≈ −0.2 to −0.3 that would be expected for a rather pure (h 11 2 ) 2 neutron configuration [37]. The hyperfine fields at 107 Cd ions implanted into gadolinium following the 98 Mo( 12 C, 3n) 107 Cd reaction were measured under similar conditions to the 110 Cd gfactor measurement.…”

“…As a first application of LaBr 3 detectors to in-beam TDPAD techniques, the hyperfine field of Cd implanted into gadolinium has been investigated. The motivation was to revisit the g-factor measurement on the I π = 10 + state in 110 Cd [13]. Even though the I π = 10 + itself is too short lived (τ ∼ 1 ns [14][15][16][17]) to apply the TDPAD method directly, in-beam TDPAD measurements can determine the effective hyperfine field at Cd nuclei implanted into gadolinium hosts.…”

“…In addition, the development of lanthanum bromide (LaBr 3 ) scintillator detectors provides an opportunity to perform these experiments under new experimental conditions through their combination of good energy and time resolution. As a first application of LaBr 3 detectors to in-beam TDPAD techniques, the hyperfine field of Cd implanted into gadolinium was investigated [80] and related to an earlier measurement of the g-factor of the I π = 10 + state in 110 Cd by an integral IMPAD method [82]. Figure 24 shows an example of a TDPAD ratio function for 107 Cd implanted into gadolinium at a nominal temperature of 6 K following the 98 Mo( 12 C, 3n) 107 Cd reaction at a beam energy of 48 MeV.…”
