This just out at PhysOrg... (see at bottom of msg) What I find funny, in a sad kind of way, is the following statement:
"So you have one set of data that tells you the mass-dependence picture doesn't work and another that tells you the density-dependence picture doesn't work," Arrington explained. "So, if both of these pictures are wrong, what's really going on?" And the experts dare say that fusion is IMPOSSIBLE under the conditions present in a CF cell? This can ONLY be said if one knows everything about nuclear interactions, and CLEARLY, they DON'T! -Mark =========================================== JLab experiment E03-103 made precise new measurements of the EMC effect in a variety of light nuclei. The results indicate that the effect does not depend on nuclear mass or density but rather on the microscopic structure of nuclei, usually neglected in high-energy measurements. This result hinges on the unusual structure of 9Be. Most of the time, it is in a configuration with two 4He-like clusters and an additional neutron orbiting around each other. The orbiting clusters yield a large radius and an anomalously low average density similar to that of the much less massive 3He. But the size of the EMC Effect in 9Be is much more similar to that of the denser nucleus of 12C. This is probably because most nucleons are contained within the high local densities of the clusters. The results suggest that the EMC effect may be entirely generated within these small, high-density clusters, where densities can briefly approach those in a neutron star.

The result was published in the November 13 issue of the journal Physical Review Letters. When comparing large nuclei to small nuclei, past measurements have shown a clear difference in how the proton's constituent particles, called quarks, are distributed. This difference is called the EMC Effect.

"So, if both of these pictures are wrong, what's really going on?" [deletions...] "We want to isolate the quark structure during the moment when the proton and neutron are very close together. If we find a large effect in such a small and simple nucleus by looking when the proton and neutron are closest together, it will demonstrate that the EMC effect does not require a large, dense nucleus - it simply requires two nucleons coming into extremely close contact," Arrington explained.
