 note = {We evaluated potentiality of lunar terminator observations by X-Ray Spectrometer (XRS) onboard SELENE (SELenological and Engineering Explorer: KAGUYA). We quantitatively estimated X-ray spectra at low solar altitudes by a numerical X-ray interaction model, and investigated critical measuring times which are required for analyses of the X-ray fluorescence lines from the target elements. The results show that effective observations at the terminator can be carried out within a double or triple measuring time as long as that at the sub solar point. Better signal-to-noise ratios at the terminator, furthermore, provide suitable situation to detect Ca and Fe, and possibly Cr and Mn., 資料番号: AA0063723041},
