Theoretical computations show that slow electron holes can avoid the acceleration that otherwise prevents their remaining slow only under these same circumstances. Although the origin of the slow electron holes is still elusive, the agreement between observation and theory about the conditions for their existence is remarkable.<a href="http://library.psfc.mit.edu/catalog/reports/2020/21ja/21ja048/abstract.php">PSFC REPORT PSFC/JA-21-48</a><br /><br />None<br /><br />If this record does not contain the full text, then the manuscript has been embargoed by the publisher thus restricting open access for 12 to 24 months after publication.
