Effective gyromagnetic ratios in odd Thallium isotopes

“…With the g-factors obtained we have calculated the penetration parameter of the 5/2 + --*3/2 + transition in 2~ (which was not included in the fit, as explained above). The value derived (2=0.46 +0.02) is consistent with that measured (2=0.5_+0.5 [5]). Unfortunately the large experimental error makes the comparison not very significant.…”

“…Following Glaudemans et al [18] the errors in the ground state magnetic moments, reported in Table 2 and used in the )r minimization procedure (see below), have been fixed at the 5 ~o level whereas the values given in literature amount to 1 ~o in 2~ [-4] and 0.05 ~o in z~176 [6,3] respectively. The correlation between the errors in the quantities 2 and M r has been neglected in the estimate of the total error in M e. It has not been possible to utilize the penetration parameter of the 5/2 + ~3/2 + transition [5] in 2~ to deduce the penetration matrix element as the corresponding M r has not yet been measured. The smallness of the coefficients of g~(7/2) and g~(7/2, 5/2) in all the equations of the system makes it impossible to extract any information about these unknowns.…”

“…The values of the penetration parameter, of the mixing ratio E2/M1 and of the reduced transition strength B(M1) have been deduced (for the latter the known lifetime [3] of the 3/2 + level has been taken into account). Corresponding data are also known in 2~ [4,5] and 2~ [6,7]. In this work we analyze the magnetic properties of 2ol-2o3 2O5T1 ' using information from M1 dipole moments as well as from penetration parameters.…”

Penetration effects in the internal conversion process of the 204 keV transition in205Tl

“…Sizeable penetration effects have been detected in Z~ (2=4.0 [6]) and in 2~ (2=6.4 [7]). On the basis of the R,~ values also larger effects could be expected in 2~…”

“…method [8]. The required normalization has been made with respect to the eK of the 279.2 keV transition in 2~ [4] whose experimental value is very accurately known [6,9]. The 3/2 + levels in 2~ and 2~…”
