Precise measurement of and for the 39.8-keV 3 transition in Rh: Test of internal-conversion theory
N. Nica, J. C. Hardy, V. E. Iacob +9
Neutron-activated sources of Ru and Pd both share the isomeric first-excited state in Rh as a daughter product. From independent measurements of both decays…
Nuclear beta decays and CKM unitarity
J. C. Hardy, I. S. Towner
Nuclear beta decays between (J^pi,T) = (0^+,1) analog states yield the best value for the Vud element of the Cabibbo-Kobayashi-Maskawa matrix. Current world data establish the corr…
Precise half-life measurement of the superallowed emitter 30S
V. E. Iacob, J. C. Hardy, L. Chen +6
We have measured the half-life of 30S, the parent of a superallowed 0+-to-0+ beta transition, to high precision using very pure sources and a 4pi proportional gas counter to detect…
Precise Test of Internal-Conversion Theory: alpha_K Measurements for Transitions in Nine Nuclei Spanning Z values from 45 to 78
J. C. Hardy, N. Nica, V. E. Iacob +1
We have been testing the theory used to calculate internal-conversion coefficients (ICCs) by making a series of measurements of alpha_K values with precision better than +/-2%. So…
Precise measurement of alpha_K and alpha_T for the 109.3-keV M4 transition in 125Te: Test of internal-conversion theory
N. Nica, J. C. Hardy, V. E. Iacob +4
We have measured the K-shell and total internal conversion coefficients (ICCs), alpha_K and alpha_T, for the 109.3-keV M4 transition in 125Te to be 185.0(40) and 350.0(38), respect…
Precise measurement of alpha_K for the 88.2-keV M4 transition in 127Te: Test of internal-conversion theory
N. Nica, J. C. Hardy, V. E. Iacob +3
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 compar…
