Abstract
The shape and normalization of the -delayed spectrum from was measured by implanting ions in a segmented Si detector. The spectrum is found to be dominated by a well-known transition to the state at in . A significant increase in the observed decay strength towards the higher end of the window means, however, that the state cannot alone be responsible for the transition. Using the -matrix framework we find that the inclusion of an extra state at is required to obtain a satisfactory description of the spectrum. Both states show large widths towards decay, exhausting significant fractions of the Wigner limit, a typical signature of clusterization. The observed Gamow-Teller strength indicates large overlaps between the two states and the ground state of .
