Abstract

The transient field perturbed angular correlation technique has been used with Coulomb excitation in inverse kinematics to perform a systematic measurement of the g factors of the first excited 2 + 1 states in the stable even-A isotopes 96−104 Ru. The measurements have been made relative to one another under matched kinematic conditions and include the first measurement of the g(2 + 1 ) = +0.47(3) in 96 Ru.

Measuredgfactors and the tidal-wave description of transitional nuclei nearA=100

“…However, aside from noting that there may be grounds to increase the previously reported g factors of the neutron-rich isotopes [6,7] by about 20%, these values are reported without adjustment in Table IX. Finally, it is to be noted that Taylor et al [25] performed transient-field g-factor measurements on the Ru isotopes in parallel with the present work. Their adopted g factors agree within the experimental uncertainties • .…”

“…[15]. It was found that extreme values must be assumed for the magnitude of g(4 (25). Combining these values with the precessions for these isotopes in Table II determines that the absolute g factors in Table II are given by g = ∆Θ/φ(∞) = ∆Θ/(−50.34 ± 3.08), where ∆Θ is in mrad.…”

“…|S(65 verse kinematics measurements described below. Specifically, the precessions measured (in inverse kinematics) for 112 Cd and 114 Cd beams, gave g( 112 Cd) = +0.365 (30) and g( 114 Cd) = +0.313 (25). Combining these values with the precessions for these isotopes in I were evaluated using the Rutgers parametrization [19] in Eq.…”

Simultaneous deorientation and lifetime measurement in98Ru using the recoil distance Doppler shift method in inverse Coulomb excitation

“…Especially, the determined hard-core values are not reliable since missing data on larger distances and the large errors do not allow a reasonable determination of these values. With the recently measured g factor for the 2 + 1 state of g = 0.47(3) [44] (another recently measured value is g(2 + 1 ) = 0.41(3) [45], one can calculate the parameters describing the hyperfine interaction strength in the Ru isotopes using Eq. (6) to C 2 = 3.3 ± 0.8 ps and C 4 = 1.5 ± 0.5 ps.…”
