Gamow-Teller Strength Distribution in Iron-group Exotic Nuclei viaMissing Mass Spectroscopy in Inverse Kinematics

为了测量铁族原子核的伽莫夫-泰勒强度分布，我们研制了一个由氘气时间投影室组成的主动靶，它既是跟踪探测器又是反应靶。我们进行了56 Fe束流的测试实验和14 O束流的先导实验。

Aiming at the measurement of the Gamow-Teller strength distribution in the Iron-group nuclei, we have developed an active target, which acts as a tracking detector and a reaction target, consisting of gaseous time projection chamber using deuterium gas. We performed a test experiment with 56Fe beam and a pilot experiment with 14O exotic beam.
