title: Suppression of β-particle events using a capillary tube in liquid scintillation α spectrometry.
abstract: A method to decrease photons generated by β particles by using a capillary tube in liquid scintillation α spectrometry is presented. Liquid scintillation counting of (241)Am and (152)Eu was performed with 200, 300, and 500 μm inner diameter (i.d.) PFA tubes as the detection cell. It was observed that the β component in the energy spectrum is located at the lower-energy region with a decreasing i.d. of the PFA tubes, and the α peak of (241)Am was separated from the β component.
