Abstract

Detailed examination of the

γ

-ray spectrum due to the reaction

{}^{9}{Be} (n, γ) {}^{10}{Be}

reveals the presence of a spin-spin interaction of magnitude

V_{I σ} = 1.65 \pm 0.15

MeV. In addition, the spectroscopic factor of the second

0^{+}

state at 6190 keV is determined to be

S_{dp} = 0.032 \pm 0.005

which suggests that this state is an intruder state.
