lPossible mechanisms suggested by Ellison & Ramaty (1985)
lshock thickness ~ κ/u         energy is too low
ldrift over shock width        rollover at ~ 100 MeV/Q
lfinite time for shock acceleration         considered here
l    (see also: Klecker et al. 1981; Lee 1983)
Why do ESP spectra roll over
at ~ 0.1 - 10 MeV/n?
