Abstract: | Summary Upgoing and downgoing deuteron whistlers were found on VLF records made by Interkosmos 5, 14 and 19 satellites even at heights below 1000 km. To account for them, a slight admixture ofD
+ ions has been introduced into the ionospheric plasma model with the usual content of only three ion speciesH
+,He
+ andO
+. Relations derived for the calculation of characteristic frequencies in a five-component plasma (e,H
+,D
+,He
+,O
+) are given as well as the values of characteristic frequencies calculated on this basis. The observed features of upgoing and downgoing deuteron whistlers could be explained by the calculation results, and it is also possible to formulate some conclusions for the purposes of plasma diagnostics.
