This work investigates ambiguities in multipole-analysis solutions for pion photoproduction, elaborates methods for constructing energy dependences of the solutions obtained and investigates the sensitivity of amplitude calculations to the experimental material and to model postulates. Based on a proposed new procedure, the multipole analysis of the processes ..gamma..p..-->..p..pi../sup 0/, ..gamma..p..-->..n..pi../sup +/, and ..gamma..n..-->..p..pi../sup -/ is carried out at energies up to 500 MeV, and the calculated amplitudes are compared with theoretical predictions. The phase of the resonant amplitude M/sup 3/2//sub H/ is determined and is compared with the corresponding ..pi..N scattering phase shift. An upper limit is estimated for possible violation of T-invariance in the electromagnetic interactions.
