520 ‡aWe have reexamined the relationship between U-shaped peak-flux-density microwave spectra and solar proton events for approx 200 large (Sp(> or = 2GHz)> or = 800 solar flux uits (sfu) microwave burst (1965 - 1979). The radio spectra fell into two basic classes: (a) U-shaped with two maxima (> or = 800 sfu) in the range from 200 MHz to> or = 10 GHz (59 percent of all events), and (b) cutoff spectra with a maximum> or = 800 sfu at f> or = 2 GHz and Sp (200 MHz) <100 sfu (18 percent). Nine percent of the events had intermediate spectra with a maximum> or = 800 sfu at f> or = 2 GHz and 100 sfu 10 MeV proton events of any size (> or = 0.01 pr per sq cm per sec per sr) are as follows: U-shaped Type II/IV (90 percent of large microwave bursts with U-shaped spectra are associated with Type II/IV events), protons (77 percent); intermediate Type II/IV (78 percent), protons (73 percent); and cutoff Type II/IV (22 percent), protons (33 percent). These statistics affirm various lines of evidence linking coronal shock waves and interplanetary proton events. They also suggest that the meter wavelength branch of the U-shaped spectrum may be attributable to second phase (vs flash phase) accelerated electrons.
