Internal conversion coefficients and penetration effect for the 279 keV transition in203Tl

Nuclear structure effect on internal conversion ofl-forbidden transitions in139La,141Pr and203Tl

“…The values of 2 and 62 obtained for the test case 2~ confirm our earlier results [18] and are in passable agreement with those published elsewhere [19,[24][25][26][27][28]. In the case of 139La Plch et al [5] have derived a nuclear penetration parameter of 2=3.1 _+0.7 from a comparison of their experimental K-shell ICC c~/~ =0.214_+0.002 and the theoretical value of ~(M1) =0.226 [8].…”

“…has been taken as a test case, as for this nucleus a similar study has already been published [18]. The 279.2 keV transition is /-forbidden too, but the effect of nuclear penetration is more pronounced and a considerable E2 part of the transition has been deduced from L-subshell ratios [19].…”

Anomalous conversion of 127 keV (E3) transition in134Cs

“…To test the validity of the present efficiency calibration of the system, a further check was also made by measuring the K/L ratio of the conversion of the 279 keV gamma transition in the 2o3 decay of Hg corresponding to the K X-ray energies 70.83, 72.87, 82.4, 85.2 and an average L X-ray energy of 11.2 keV. This value is found to be 3.41+_0.01 which [25]. This value is found to be 3.41+_0.01 which [25].…”

“…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~…”
