Abstract

The d(α,⁶Li_3.56/*)π⁰ reaction has been studied at E(c.m.) = 1.2 and 1.9 MeV above threshold with an alpha-particle beam incident on a deuterium cluster-jet target in CELSIUS. Complete differential cross sections were measured at both energies, integrated to σ = 228 ± 6 + 70 nb and 141 ± 12 + 42 nb respectively. Observed large anisotropies are discussed in relation to the cluster structure of the ⁶Li* halo. (C) 2000 Elsevier Science B.V.
