abstract = "This paper deals with a detailed analysis of spectral and imaging
observations of the November 5, 1998 (H alpha 1B, GOES M1.5) flare
obtained over a large spectral range, i.e., from hard X-rays to
radiometric wavelengths. These observations allowed us to probe
electron acceleration and transport over a large range of
altitudes that is to say within small-scale (a few 10(3) km) and
large-scale (a few 10(5) km) magnetic structures. The observations
combined with potential and linear force-free magnetic field
extrapolations allow us to show that: (i) Flare energy release and
electron acceleration are basically driven by loop-loop
interactions at two independent, low lying, null points of the
active region magnetic field; (ii) < 300 keV hard X-ray-producing
electrons are accelerated by a different process (probably DC
field acceleration) than relativistic electrons that radiate the
microwave emission; and (iii) although there is evidence that hard
X-ray and decimetric/metric radio-emitting electrons are produced
by the same accelerator, the present observations and analysis did
not allow us to find a clear and direct magnetic connection
between the hard X-ray emitting region and the radio-emitting
sources in the middle corona.",
