INSTITUTE (1USABRK,2SWTWUR,2SWTUBE,1USALAS) C254500100011
FACILITY (CYCLO,1USABRK) The Lawrence Berkeley Laboratory 88- C254500100012
inch cyclotron. C254500100013
METHOD (ACTIV,CHSEP) The 248Cm and 249Cf targets were C254500100014
irradiated at the Lawrence Berkeley Laboratory C254500100015
88-inch cyclotron with 97-, 104-, 113-, and 122-MeV C254500100016
180 ions. In addition, the 249Cf was irradiated with C254500100017
91- and 150- MeV 18O ions. C254500100018
CORRECTION All quoted energies have been corrected for the total C254500100019
energy loss of about 15 MeV in the Havar window, C254500100020
cooling gas, and Be target backing. No corrections C254500100021
were made for the energy losses of 1 to 2 MeV in the C254500100022
targets. C254500100023
ERR-ANALYS (DATA-ERR) The standard deviation associated with the C254500100024
quoted absolute cross sections is estimated to be C254500100025
+-12%, in addition to the statistical standard C254500100026
deviation s given in the tables, which is based on C254500100027
the decay analysis. C254500100028

SAMPLE Similar to EXFOR entry A0173: The target contained C254500200004
0.924 mg/cm2 of 'Cm' /96.5% 248-Cm,3.5% 246-Cm/ in C254500200005
the form Cm-F/3 deposited with a diam. of 6.5 mm on C254500200006
2.65 mg/cm2 'Be' foil. C254500200007
(96-CM-248,ENR=0.965) C254500200008
(96-CM-246,ENR=0.035) C254500200009
Gold foils, 19.5 mm in diam. and 2 mg/cm2 thick, were C254500200010
placed 3 mm from the target to catch the recoiling C254500200011
products. C254500200012
FLAG (1.) No absolute gamma-ray intensity data are C254500200013
available for the 0.177-MeV photon which we measured, C254500200014
but the 0.177-MeV level in 251Cf is deexcited by a C254500200015
0.177-MeV gamma transition (72.5%) and a 0.153-MeV C254500200016
gamma transition (27.5%) . The total conversion C254500200017
coefficient for the 0.177 gamma transition was C254500200018
estimated to be =8 based on a measured alphaK of 6.0 C254500200019
and an estimated (alphaL+alphaM) of 1.7 for an M1(+ C254500200020
E2) transition. The decay of 251Bk is assumed to C254500200021
primarily populate the 0.177- MeV level. If there is C254500200022
appreciable feeding of the ground state or other C254500200023
levels which do not deexcite via the 0.177-MeV C254500200024
transition, our quoted cross sections will be C254500200025
correspondingly too 1ow. C254500200026
(2.) Corrected for contribution from the Bk parent. C254500200027
(3.) Radiation from daughter activity was measured. C254500200028
(4.) Corrected for contribution from decay of the Cf C254500200029
parent. C254500200030
(5.) Corrected for contribution from decay of the Es C254500200031
parent. C254500200032
(6.) Corrected for contribution from 7.04-MeV alpha C254500200033
group of 252Fm. C254500200034

SAMPLE (98-CF-249,ENR=1.0) The 249Cf target contained 0.52 C254500300004
mg/cm2 in the form of CfF3 deposited with a diameter C254500300005
of 6.5 mm on 2.13 mg/cm2 Be foil. C254500300006
FLAG (1.) The total cross section for 250Es when both C254500300007
isomers were not measured, the ratio of the cross C254500300008
section of the 6+ (8.6 h) to the sum of the cross C254500300009
sections of the 6+ and 1- (2.1 h) isomers was taken C254500300010
to be 0.17+0.17 for the 91- and 97-MeV bombardments, C254500300011
consistent with our measured values of 0.17- +0.05 at C254500300012
104 MeV, 0.32+0.16 at 122 MeV, and 0.43-+0.13 at 150 C254500300013
MeV. An interpolated value of 0.25-+0.17 for 113 MeV C254500300014
was used. C254500300015
(2.) Radiation from daughter activity mas measured. C254500300016
(3.) Corrected for contribution from 7.04-MeV alpha C254500300017
group of 252Fm. C254500300018
