摘要：
The effects introduced by 4pi charged-particle detector arrays such as the Microball on lifetime measurements by Doppler-shift attenuation techniques are discussed. The effect originates from the lower efficiency for detecting charged particles at backward angles. Procedures for correcting for such "bias" are described. (C) 2003 Elsevier B.V.
