SAMPLE A 210- mug/cm2-thick, self-supported natural silicon A068500100023
target, tilted by +/- 45 degree (depending on the A068500100024
detector position). A liquid-nitrogen cold trap close A068500100025
to the target holder reduced the target contamination A068500100026
on carbon to minimum. A068500100027
MONITOR (14-SI-0(3-LI-7,EL)14-SI-0,,DA) The scattering at +/- A068500100028
15 degree, concerning the present bombarding energies, A068500100029
can be considered as being pure Rutherford. A068500100030
DETECTOR (TELES,SIBAR,SIBAR) The DE silicon detector was 10 A068500100031
micrometers thick, while the E detector was 300 A068500100032
micrometers thick measuring the forward-angle A068500100033
scattering, A068500100034
(SIBAR) A thin, 20- or 25- micrometers - thick siliconA068500100035
detector measuring the backward scattering. The choiceA068500100036
of the thickness of the backward detector was such as A068500100037
to allow light particles, like alphas from breakup A068500100038
transfer and other contaminant reactions (7Li+12C), to A068500100039
go through while Li particles stop in the detector. A068500100040
FACILITY (VDGT,2GRCATH) TN11/25 HVEC 5.5 MV A068500100041
METHOD (EXTB) 7Li2+ and 7Li3+ beams. Beam currents were of A068500100042
the order of 30 nA. A068500100043
(EDE) The alpha group was well discriminated in the A068500100044
forward detectors with the DE-E technique. A068500100045
HISTORY (20040708C) A068500100046
(20040708R) Data tables were recieved from A.Pakou A068500100047

STATUS (TABLE) From A.Pakou A068500100049
(APRVD) By A.Pakou A068500100050
ADD-RES (THEO,POT) The results were analyzed in a A068500100051
double-folding model by using the BDM3Y1 interaction. A068500100052
Previous data of 6Li+28Si, 6,7Li +138Ba, and A068500100053
6,7Li+208Pb were also considered in the same A068500100054
theoretical framework, in order to draw meaningful A068500100055
comparisons. An anomalous behavior for both the real A068500100056
and imaginary part of the optical potential develops A068500100057
for the weakly bound nuclei 6,7Li in the vicinity of A068500100058
the barrier, which in total contradicts the A068500100059
conventional threshold anomaly applied to stable A068500100060
systems. This behavior may be described only A068500100061
qualitatively by dispersion relations. A068500100062
