As we have
experienced that commercial 9Be carriers in use for
accelerator mass spectrometry (AMS) contain elevated levels
of 10Be/9Be,
we have published values of these compared to customised 9Be
carriers from minerals already two times:
S. Merchel, M. Arnold, G. Aumaître, L. Benedetti, D.L.
Bourlès, R. Braucher, V. Alfimov, S.P.H.T. Freeman, P. Steier, A.
Wallner, Towards more precise 10Be and 36Cl data
from measurements at the 10-14 level: Influence of sample
preparation, Nucl.
Instr. Meth. Phys. Res. B. 266 (2008) 4921-4926. S. Merchel, R. Braucher, J. Lachner, G. Rugel, Which is the best
9Be carrier for 10Be/9Be accelerator mass
spectrometry?, MethodsX 8 (2021) 101486. These results have yet shown that 10Be/9Be can vary from LOT to LOT. Hence, to keep the AMS community up-to-date we are encouraging to communicate 10Be/9Be measured at any AMS facility. So, if you have any new 10Be/9Be data of commercial 9Be carriers, please let me know and I will add it to the table below to overcome the necessity to write a third paper on this topic. ;-)
