Conclusions on ESP spectra É
1.
Finite-time shock acceleration
model
• power law spectrum at low energy
• faster dropoff at high energy
2.
Expect Ec /A
°
t2/(α+1) (Q/A)2α/(α+1)
3. For 3 events, able to
simultaneously fit measurements
of C, O, and Fe ions
4. Fits
to weak events: Infer λ as typical IP
values
5. Fit to strong event: Infer much
lower λ, consistent with
expectations for proton-amplified waves
