 note = {The spacecraft potential has been used to derive the electron density surrounding the spacecraft in the magnetosphere and solar wind. The previous studies have examined the relationship between the spacecraft potential and the electron density in the distant tail regions and obtained an empirical formula to show their relation. However the electron density obtained by the empirical formula is often overestimated in the near tail regions with high electron temperature, In this study, we investigate the relationship between the Geotail spacecraft potential and the electron density/temperature in the near tail regions during the period from November 1994 to February 1997, and improve the empirical formula considering the electron temperature. Then we discuss on the investigation of distribution of low energy plasma in the near tail region by comparing the electron density obtained by the improved empirical formula with that measured by the low-energy particle instrument onboard the Geotail spacecraft., 資料番号: AA0049206025, レポート番号: JAXA-SP-05-001E},
