In on-line nuclear orientation experiments the relaxation process is of great importance. During implantation of the radioactive beam, the nuclear sublevel populations attain a secular equilibrium. For this case secular orientation parameters are introduced: B-lambda(sec)=rho(lambda)B(lambdalambda)(th). Previously attenuation coefficients rho(lambda) have already been tabulated, but only for lambda=2,4. In the last few years the number of nuclear orientation experiments in which beta or alpha particles are studied has increased. For these experiments the terms with lambda=1, 3, 6, and 8 are also necessary. Therefore, we have calculated the values of rho(lambda) in full scope.
