Ai. Sattarov et al., EXTRAPOLATION METHOD FOR DETERMINING NUCLEAR VERTEX CONSTANTS BY MEANS OF PADE APPROXIMANTS, Physics of atomic nuclei, 60(7), 1997, pp. 1096-1102
A method for extrapolating the differential cross sections for single-
particle-transfer reactions of the type A(x, y)B to the singularity of
the reaction amplitude in cos theta (theta is the c.m.s. scattering a
ngle) closest to the physical region is developed on the basis of Pade
approximants, and the error of extrapolation is estimated reliably. T
he proposed method is applied to specific reactions. The squared modul
i of nuclear vertex constants are determined for the virtual decays t-
->d+n, He-3-->d+p, Li-6-->alpha+d, and Li-7-->alpha+t.
