Discussion

D. Smith: I know spontaneous emission maximizes at about 90 ~ However, if B is present, amplification maximizes at about 0 ~ with respect to B. Rosenberg: No. D. Smith: According to Yip the growth rate maximizes along the magnetic field.

Rosenberg" Direction of B does not make that much difference. D. Smith: Since the growth rate occurs in an exponential, a small change makes a lot of difference, and the waves must be amplified to obtain observed brightness temperatures.

Melrose: Electrons would be unmagnetized in this case and then one should add all harmonics. The result is equivalent, semi-quantitatively at least, to ignoring the spiralling motion of the electrons entirely. Then Rosenberg is right.

There are three kinds of observations that provide indirect evidence for the contentions that (a) some type III radiation is fundamental radiation; and (b) type III's are at times emitted simultaneously as fundamental and second-harmonic plasma radiation.

It is demonstrated by a numerical simulation that both the whistler waves and plasma waves are excited by a common solar electron beam. The excitation of the whistler waves is ascribed to the loss-cone distribution which arises at a later phase of the passage of the beam at a given height due to a v

Using the data from our experiments on the IMP-6 (Explorer 43) satellite, we have examined over 200 type III bursts at kilometric wavelengths, including 16 bursts which were accompanied by >18 keV electron events with sharp onsets, in a search for the electrostatic waves which, according to theory,
