Abstract

From a forward dispersion relation applied to

p + d

and

p

+

{}^{3}{He}

scattering amplitudes we obtain accurate empirical values for the

{}^{3}{He}

-

dp

and

{}^{3}{He}

-

d^{*} p

coupling constants. The corresponding asymptotic normalization parameters for the

S

-state wave-function component of

{}^{3}{He}

are found to be

C^{2} ({}^{3}{He}, d p) = 3.40 \pm 0.20

and

C^{2} ({}^{3}{He}, d^{*} p) = 5.85 \pm 0.25

.
