TITLE The cross section for the reaction B-10(p,alpha)Be-7 atO091700100003
proton energies below 200 keV. O091700100004

FACILITY (CCW,2UK BIR) Protons extracted from a radio- O091700100008
frequency ion source were accelerated in a vertical O091700100009
two-stage vacuum tube. O091700100010
SAMPLE The B-10 targets were prepared by electromagnetic O091700100011
deposition of the isotope on copper. Two thin targets O091700100012
of 90 ug/cm2 and 120 ug/cm2 (accurate to 10%) and O091700100013
one thick target,400 mug/cm**2, were used. The O091700100014
thickness of this last target was determined by O091700100015
weighing the backing foil before and after deposition. O091700100016
DETECTOR (SCIN) The alpha particles were detected by a zinc O091700100017
sulphide screen and photomultiplier. O091700100018
METHOD (BCINT) Target currents were always measured with the O091700100019
target at a sufficiently large positive potential to O091700100020
retain secondary electrons. O091700100021

COMMENT - By authors. Relative value of the cross section at O091700300005
lower energies were obtained using a thick target and O091700300006
the analyser for proton energies down to 120 KeV. For O091700300007
energies below 120-KeV a simple target chamber O091700300008
employing range discrimination, and with a much larger O091700300009
solid angle than the analyser was used. The alpha O091700300010
particles were detected by a zinc sulphide screen and O091700300011
photomultiplier. These observations were fitted to the O091700300012
absolute determinations at 180 and 205 KeV. O091700300013
ADD-RES The data are presented as Gamov plot too. O091700300014
