Studies Towards a Method for Radiocalcium Dating of Bones
We made preliminary AMS measurements of 41 Ca/Ca ratios in bone and limestone specimens with the Argonne Tandem-Linac Accelerator System (ATLAS). We were able to avoid pre-enrichment of 41 Ca used in previous experiments due to a substantial increase in Ca-beam intensity. Most of the measured ratios lie in the 10 -14 range, with a few values below 10 -14 . In general, these values are higher than the ones observed by the AMS group at the Universi…
Radioisotope Detection with the Argonne FN Tandem Accelerator
A standard heavy ion nuclear structure facility has been used to detect several long-lived radioisotopes by counting the accelerated ions. The problem of eliminating strong isobaric background beams has been solved by combining the energy loss dispersion through a uniform A l foil stack with the high momentum resolution of an Enge split-pole magnetic spectrograph. Radioisotope concentrations in the following ranges have been measured: 14 C/ 12 C …
