  Our collaboration has set up a focal plane detection system and a focal plane
polarimeter at the large acceptance Big-Bite Spectrometer at AGOR. The detector
systems are equipped with a high performance readout and online data processing
system, which allows polarization transfer and charge transfer measurements at
extreme forward angles with high precision. Preliminary results on GT+ strength
distributions obtained in (d,2He) measurements revealing the fine structure of
the distributions are presented. Their relation to recent calculations of
stellar weak interaction rates is discussed.
