Precise measurement of alpha_K for the 88.2-keV M4 transition in 127Te: Test of internal-conversion theory Open
We have measured the K-shell internal conversion coefficient, alpha_K, for the 88.2-keV M4 transition from the 106-day isomer to the ground state in 127Te to be 484(6). When compared with Dirac-Fock calculations of alpha_K, this result agr…

Test of internal-conversion theory with a measurement in <sup>111</sup>Cd Open
We have measured the K-shell and total internal conversion coefficients for the 150.8-keV E3 transition in 111Cd: αK = 1.449(18) and αT = 2.217(26) respectively. The αK value agrees well with Dirac-Fock calculations, in which the effect of…

Precise measurement of branching ratios in the beta decay of 38Ca Open
We present the full description of a measurement of the branching ratios for the beta-decay of 38Ca. This decay includes five allowed 0+ --> 1+ branches and a superallowed 0+ --> 0+ one. With our new result for the latter, we determine its…

Testing CVC and CKM Unitarity via superallowed nuclear beta decay Open
\nCurrently, the most restrictive test of the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix is anchored by nuclear beta decay. Precise measurements of the ft-values for superallowed beta transitions between analog 0+ states are u…
