Abstract
A method for the description of the gamma-ray line-shapes observed in coinc idence lifetime measurements using the Doppler-shift attenuation method is proposed. The case where a gate is set on a transition which feeds directly the level of interest is considered in detail. The formalism for lifetime determination in the general framework of the differential decay-curve meth od is developed. The method is illustrated by an application to data simula ted for the case of the Cd-116(O-16, 4n)Ba-128 reaction at a beam energy of 72 MeV observed with a multi-detector set-up.
