É but wait Ð thereÕs more!
Key processes of interplanetary transport
• Scattering
• Focusing (a.k.a. mirroring)
• Solar wind effects
- Convection
- Adiabatic deceleration
Note: mean free path is ~ 0.1 to 3 AU
Aim to quantitatively explain profiles of intensity & anisotropy vs. time

•If the mean free path were much smaller than 1 AU, the distance É, then you could use the diffusion approx. É
•If much larger, free streaming
•But when the mean free path is of the same order as the distance of interest, the problem is more difficult
