Abstract

The

{}^{4}{He} (\vec{d}, γ) {}^{6}{Li}

reaction at low energies is discussed using a direct capture model and assuming that the process is predominantly

E 2

. A good description of the total cross section for

1 MeV < E_{c . m .} < 9 MeV

is obtained. The inclusion of a

D

-state component into the

α + d

cluster model wave function of

{}^{6}{Li}

originates nonvanishing tensor analyzing powers.

T_{20}

depends linearly on the

\frac{D}{S}

asymptotic ratio

ρ

of

{}^{6}{Li}

and increases in magnitude with energy. It is suggested that the measurement of

T_{20}

or

A_{yy}

can determine the sign and magnitude of

ρ

.
