Determination of asymptotic normalization coefficients for the $^{7}$Li$\to α+ ^{3}$He channel

Asymptotic normalization coefficients (ANCs) $C_{3/2}$ and $C_{1/2}$ for the channels $^7$Li$(3/2^-;0$ MeV)$\to α+^3$H and $^7$Li$(1/2^-;0.478$ MeV)$\to α+^3$H, respectively, were determined by analyzing elastic $α^3$H- scattering data using three different methods. All three methods yield similar r
