DETECTOR (HPGE) Gamma spectra were measured by using four large O091800200006
volume detectors O091800200007
SAMPLE In the set of measurements the target used was placed O091800200008
at 90 degree to the beam axis. It was produced by O091800200009
evaporating Nb/2-O/5 on a 0.4-mm thick tantalum O091800200010
backing, which was cooled with water during the whole O091800200011
experiment. It should be noted that the use of the O091800200012
Nb/2-O/5 target requires corrections for yield O091800200013
contribution from the O-17(p,p'gamma)O-17 reaction. O091800200014
The thickness of Nb in the Nb/2-O/5 target was found toO091800200015
be 125+-5 mug/cm**2. O091800200016
By considering the target stoichiometry one obtains a O091800200017
target total thickness of 180+-6 mug/ cm**2, which O091800200018
corresponds to a target thickness delta-E of 20 and 12 O091800200019
keV at a beam energy of 1.5-3-MeV, respectively. O091800200020
All targets used in the present work were also checked O091800200021
at the end of all measurements. No significant O091800200022
deterioration effects were found. O091800200023

DETECTOR (HPGE) Gamma spectra were taken by means of one O091800300006
detector of 80% relative efficiency that was placed O091800300007
either at 55 or 90 degree to the beam axis. O091800300008
SAMPLE In the set two different Nb targets positioned at 45 O091800300009
degree to the beam axis were used, namely, Nb/2-O/5 andO091800300010
a metallic Nb. The latter target was made by electron O091800300011
gun evaporation of metallic niobium of extreme high O091800300012
purity. The fluorine level in the metal was less thanO091800300013
1%. The energy region covered by the measurements O091800300014
using the metallic Nb was from 1.4 to 4.9 MeV. Both O091800300015
targets were on 0.4-mm thick Ta backings, which were O091800300016
cooled with air during the measurements. It was found O091800300017
that the thickness of Nb in the Nb/2-O/5 target was O091800300018
106+-6 mu-g/cm**2. The target had a total thickness of O091800300019
151+-7 mu-g/cm**2. For the metallic target the analysisO091800300020
yielded a thickness of 371+-18 mu-g/cm**2, which O091800300021
corresponds to lost energy =31 and 20-KeV at proton O091800300022
beam energies of 1.5 and 3-MeV, respectively. O091800300023
All targets used in the present work were also checked O091800300024
at the end of all measurements. No significant O091800300025
deterioration effects were found. O091800300026
CORRECTION In the case of the Nb/2-O/5 targets corrections for O091800300027
yield contributions from the O-17(p,p'gamma)O-17 O091800300028
reaction were necessary. The required corrections were O091800300029
performed with additional yield measurements carried O091800300030
out with a W-O/3 target, the thickness of W was found O091800300031
to be 153+-5 mu-g/cm**2 O091800300032
COMMENT -By authors. The measurements were carried out with O091800300033
metallic Nb in order to avoid any uncertainties arisingO091800300034
from the intruding O-17(p,p'gamma)O-17 reaction. AfterO091800300035
calculation of the effective bombarding energy, the O091800300036
yield data were transformed to cross sections by O091800300037
normalization to the Nb/2-O/5 angular distribution O091800300038
data. There were found to coincide within 5% with O091800300039
those determined from the angular distribution data O091800300040
obtained with the Nb/2-O/5 target. O091800300041
ERR-ANALYS (ERR-S) The cross sections values having an error of O091800300042
less than 5% are the means of at least two independent O091800300043
measurements. O091800300044

ANALYSIS The analysis of the corrected angular distributions O091800500004
yielded new values for the A2 and A4 coefficients, O091800500005
which, however, are still statistically constant in theO091800500006
energy range 2-3 MeV, with mean values A2=0.315(10) andO091800500007
A4=0.181(9) (see digitized data) O091800500008
Based on this fact, it was further assumed that O091800500009
the angular distributions of the 2(1)+ -> 0(1)+ gamma- O091800500010
transition of the 94Mo nucleus at Ep =< 2 MeV and O091800500011
Ep >= 3 MeV would not deviate significantly from those O091800500012
measured at Ep= 2-3 MeV, i.e., they could also be O091800500013
described by W(theta)=[1 + 0.315(10) x O091800500014
x P2(cos(theta))-0.181(9) x P4(cos(theta))] O091800500015
