The g-Factor of the 80.1 keV Level in ¹⁴⁴Pr

Abstract

The g-factor of the 80.1 keV level in 144Pr has been determined in an IPAC study of the 53.4-80.1 keV cascade. With an external magnetic field of 21.7(3) kG the precession angle ωτ was measured to be -0.045(12). The result g = -1.2(4) agrees well with that calculated in terms of coupling of the effective moments of the odd particles, g = -1.43(7). From the directional correlation of the 53.4-80.1 keV cascade the mixing ratio of the 53.4 keV transition was determined, δ(E2/M1) = 0.043(3).

A unified model calculation of states in odd-mass technetium isotopes

“…However, using this set of basis states a low lying 5/2 + state does not appear in any natural way. We have shown before [2,3] that many of the characteristics of 95Tc and 99Tc can be accounted for in a model where (g9/2)3 j configurations are coupled to the core undergoing quadrupole oscillations. The drastic lowering of the first 5/2 + level as compared to the 11/2 + and 13/2 + levels observed in the heavier isotope, however, was not reproduced in these calculations.…”

“…The multichannel goniometer (MCG) developed at this labora-tory [15] was used to study the perturbed angular correlation of the weak 142.5-1 291.5 keV cascade to determine the g-factor of the 1291.5 keV state in 59C0.…”

“…Gz is the attenuation coefficient corresponding to a randomly oriented static magnetic dipole interaction [30] l/(l+(NwLt)')The results from the least squares fit are Igl =1.71 (20) and I wL~(Co) I = 1.37(17). The data obtained from the measurements with an external magnetic field were analysed according to the method described in ref [15]. using the function W(0, H )[31] appropriate for an angular correlation perturbed by a transverse magnetic field H. In order to increase the accuracy in wLt for the The g-factor of the 1 291.…”
