• Collaboration: MoNA / Sherry Yennello's group / HiRA
• use reaction similar to typical MoNA kinematics, maybe expand the EOS program later
• Purpose: examine sensitivity of Y(n/n) to L of symmetry energy
• 30/40 S + 9Be
• Look at Y(n/n) in PLF region, maybe make rapidity cuts
• HiRA group suggestions: consider including shadow bars? Also, consider something to veto protons (maybe the first later in MoNA)

• Test out AT-TPC and examine fusion barriers in Pb, Cs
• H gas in chamber, look at tracks made, determine energy of fusion
• Implications on r process
• Calibration: 208Pb, has known fusion cross-section

• Lee's: maybe in fall. Alan Wuosmaa's: maybe in spring 2013. Can keep setup in S2
• No updates on RIKEN experiment

• Modeling Sn+Sn and varied lots of parameters. Looking primarily at DR(n/p):
• varied mean field stiffness and momentum-dependence
• vary Sint with gamma
• cross-sections in screened/free/Rostock model with and without clusters
• dependence of DR on energy and momentum-dependence (or -independence)
• Repeat with clusters and coalescence-invariance: DR varying with gamma, cross-section type
• Look at single yield ratios (pp, nn, np, tt, 3He3He, t3He)
• Bill and Zibi suggest other calculations to run
