I was reading a bit about this technique on another forum, but it's a bit over my head. I was wondering if anybody is familiar with it, what it's advantages and disadvantages are, and is it our best/most accurate technique, yet?
And from the YEC crowd, what are your objections to it?
Here are a few links dealing with it:
http://indigo.uic.edu/...3/1-s2.0-S0016703712003067-main.pdf
http://arxiv.org/ftp/arxiv/papers/1101/1101.2933.pdf
http://www.phy.anl.gov/atomic/PUBS/pub2000-07.pdf
From what I can tell, it's an improvement over AMS measurements, measuring instead with lasers, used (I think exclusively, so far) on the isotopes of inert gases, specifically Ar39, Kr81, and Kr85. The primary improvement being eliminating some contamination issues. It seems to be a much "cleaner; less noise" measurement. Though I would imagine there would still have to be some background noise.
The relatively short half lives of these isotopes (particularly Kr85) makes it useful for geologically recent events. I would think that it would also be useful as another crosscheck for carbon dating.
It lists quite a few possible applications, not all of which concern dating. It mentioned using for testing water and ice, but don't get how that would work, unless it was for non-age-testing purposes.
It seems to me that it will be particularly useful for more accurate dating of very recent events (last couple hundred years). And of course, it's always good to have another test available when the geology creates limitations with other methods.
So, if anybody with a little more science training than I have would be interested in checking it out, and maybe putting it layman's terms for us, it would be much appreciated.

Would you mind adding your own brief description of this dating technique to your opening message? I know you say "it's a bit over my head," but you need only provide enough to give people a rough idea.

Sure, I'll review the sources and see what kind of summary I can come up with in the next 24 hours or so.

I've entered a brief summary of what I can glean from the papers. Let me know if there is something further you'd like me to address, and I'd be happy to do so.
