In. Izosimov et al., STRUCTURE OF THE BETA(-147G (T1()(EC) DECAY STRENGTH FUNCTION OF TB)2-SIMILAR-OR-EQUAL-TO-1.6H)/, Journal of physics. G, Nuclear and particle physics, 24(4), 1998, pp. 831-845
The strength function S-beta(E) for the beta(+)(EC)-decay of Tb-147g (
T-1/2 similar or equal to 1.6 h) is measured by the method of total ga
mma-rays absorption. The same strength function is deduced from the an
alysis of the Tb-147g decay scheme and Gd-147 level scheme. The thus d
erived strength functions are in quite good agreement with each other.
Also, theoretical calculation of S-beta(E) by the microscopic quasipa
rticle-phonon model is carried out. The most characteristic properties
of both the experimental and theoretical strength functions are prono
unced resonances in S-beta(E).
