Final Look

Error estimate based on previous analysis using standard solid polarized targets results indicated in first write-up based on an asymmetry A_zz

with an absolute systematic uncertainty estimated from,

To obtain tensor polarization by optimizing vector polarization we expect a tensor polarization of P_zz=2-(4-3P²)^1/2 assuming a Boltzman distribution at thermal equilibrium.

But not at thermal equilibrium under experiment (trying not to under estimate error)
Analytic relation not applicable for tensor Optimization (hole burning)

General limitations for all tensor polarized experiments to keep in mind:
1.) Ideal P_zz =2.5%-5%
2.) Vector Optimized P_zz =6.5%-12%
3.) Tensor Optimized P_zz =15%-25%
4.) Negative tensor polarization not yet achieved without hole burning (very unstable)

Best estimates for Cumulative Absolute Uncertainty (still just an estimate)

(No estimate included for background contamination or small coherent length nuclear effects)
The structure of the ground state wave function in nuclei at small interparticle distance is still an unsolved problem which with the right experiment could be investigated.

What about other observables?

Still lots of experimental possibilities with tensor polarization:
1.) Cross section or Asymmetry (A_xx) based on positive Vector Optimized only "http://www.jlab.org/exp_prog/proposals/97/PR97-102.pdf"
2.) Electrodisintegration "http://dspace.mit.edu/handle/1721.1/34390"
3.) Photodisintegration "http://iopscience.iop.org/1742-6596/295/1/012106/pdf/1742-6596_295_1_012106.pdf"
4.) CLAS photoproduction "http://iopscience.iop.org/1742-6596/295/1/012115/pdf/1742-6596_295_1_012115.pdf"

Keep in mind that optimization in tensor polarization can lead to P=0 for other materials but not ND₃. This can be considered for photon experiments.
Optimal tensor polarization achieved with deuterated 1,2-ethanediol, (CD₂OH)₂, at 0.12 K in a magnetic field of 25 kG.

Need to figure out what is interesting theoretically and not yet done...
