                         measured with rocket-borne electron density probes in two 
                         campaigns conducted from Alcantara (2.31°S; 35.2°W), Brazil. A 
                         Black Brant X sounding rocket was launched on 14 October 1994 at 
                         1955hrs (LT) to investigate the phenomenon of high-altitude 
                         equatorial spread-F events. A Brazilian-made SONDA III rocket was 
                         launched on 18 December, 1995 at 2117 hrs (LT). Ground equipment 
                         was operated during these campaigns to ensure that the rockets 
                         were launched under conditions favourable for the generation of 
                         plasma bubbles in the F-region. The rockets, in both occasions, 
                         passed through several developing plasma bubbles. The k-spectra of 
                         plasma irregularities were obtained by spectral analysis of the 
                         electron density fluctuation data. The electron density 
                         irregularites associated with plasma bubbles had sharp lines in 
                         their k-spectra, extending over a wide range of altitudes. 
                         Existing theories on the generation of small scale irregularities 
                         by cascading predict a flat k-spectrum. Present results may be 
                         indicative of the presence of preferred wave modes in developing 
                         plasma bubbles.",
