3. c)
We changed the sixth term being passed to the 'SB' command. (PD below) to 0.01. SB <PX><PA><r12><PY><PB><r34><PT><PD><r56><PG><PZ> This pulled the three sets of rays in the image very close together.
4. a)
Target 1H Projectile 20Ne Ejectile g Recoil 21Na Projectile Kinetic Energy 40MeV We plotted theta4(recoil angle) vs theta3(gamma angle) It seems the larger the recoil cone, the larger the gamma cones (equally forward & backward) Ours did fit both separators. If it didn't, the larger the energy, the smaller the recoil cones.
4. b)
We plotted theta4 (recoil angle) vs E4 (recoil E), and found dE/E = +/- 0.7%

7. Q2 converged at 0.1 T with obj at 0.3E-3, Mas. Res.Power at FP2= 2841, REsol. by max. ray= 950. This was after the fit, minimizing the inverse of the first order resolving power.
