SAMPLE A 4 cm diameter and a 15 cm length long cylindrical O166000100018
gas cell filled with He-4 at the pressure of 150 mbar. O166000100019
The gas target cell was connected to the end of the O166000100020
beam pipe through a approx. 5 mum(nominal thickness) O166000100021
Ni entrance window. O166000100022
PART-DET (N) O166000100023
DETECTOR (D4PI).The neutron were detected by the Polycube 4-pi O166000100024
thermalization counter, consisting of 12 cylindrical O166000100025
proportional counters filled with He-3 at the pressure O166000100026
of 4 bar embedded into a 40*40*40 cm**3 polyethylene O166000100027
moderator. O166000100028
(MCPLT) Two micro-channel-plate (MCP) detectors O166000100029
(MCP1 and MCP2) were located upstream along the beam O166000100030
pipe, at 150 and 50 cm from the Ni entrance window, O166000100031
respectively O166000100032
FACILITY (VDGT,2ITYLNS) O166000100033
INC-SOURCE The Li-8 beam was delivered by the EXCYT ISOL facilityO166000100034
at LNS in Catania. It was produced by injecting a C-13+O166000100035
primary beam of 45 MeV 1/amu on a graphite target. O166000100036
METHOD (EXTB) secondary Li-8 beam O166000100037
(PLSED) The neutrons were moderated and adsorbed in theO166000100038
detector. O166000100039
COMMENT *By authors*.The experiment consisted of the three O166000100040
types of measurements- O166000100041
- a measurement without beam O166000100042
- a set of projectile correlated measurements without O166000100043
He-4 O166000100044
- a set of projectile correlated measurements with O166000100045
He-4 O166000100046

COMMENT *By authors*.The new determination cross section value O166000200004
turns out to be about 10% smaller than that given in O166000200005
previous letter(See reference-J,PL/B,664,157,2008), O166000200006
while the effect of the sources of systematic O166000200007
uncertainties has proved to be negligible. O166000200008
*By authors*.In the present neutron-inclusive O166000200009
measurement, the background contribution has been O166000200010
carefully identified and evaluated. Since different O166000200011
sources of systematical uncertainties and of backgroundO166000200012
are involved, the present data strongly confirm and O166000200013
support the complementary B-11 inclusive data. O166000200014
