 note = {It was revealed in the preset Moessbauer investigation that four iron-bearing minerals were contained in both the unknown samples named '4A' and '4B' for the second HASPET (Hayabusa Asteroid Sample Preliminary Examination Team) competition; they are olivine, pyroxene, kamacite and troilite. For purpose of the identification, Moessbauer spectra were measured for mineral samples being ensured to be what it is. It was concluded that the samples of 4A and 4B should be meteorite materials; the former be a stony meteorite while the latter be an iron meteorite from our Fe-57-Moessbauer measurement and analysis., 資料番号: AA0063920002, レポート番号: JAXA-SP-05-021E},
