A novel approach to medical radioisotope production using inverse kinematics: a successful production test of the theranostic radionuclide 67Cu
G Souliotis, M Rodrigues, K Wang +7
A novel method for the production of important medical radioisotopes has been developed. The approach is based on performing the nuclear reaction in inverse kinematics, namely send…
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…

Precise measurement of branching ratios in the beta decay of 38Ca
H. I. Park, J. C. Hardy, V. E. Iacob +8
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…
