摘要
本文报道了用低本底Ge(Li)γ谱仪重新测量吉林陨石2号和5号样品中宇宙成因核素^(26)Al的比活度,对以前发表的结果进行了修正。测得的^(26)Al平均比活度为32.4dpm/kg,与国外报道的平均值在误差范围内符合,同时,估算和讨论了吉林陨石的宇宙线暴露年龄。
New data are reported on cosmogenic nuclide 26A1 from redetermination on Specimen No. 2 and 5 of Jilin meteorite by nondestructive γ-ray speetrometry. Cosmic ray expo-sure age of the Jilin meteorite has also been estimated and discussed.
