FACILITY (CYCLO,2JPNTOK)The sector focusing cyclotron was used 2270200100009
for irradiation experiments 2270200100010
(ISOCY,2JPNTOH) An azimuthally varying field cyclotron 2270200100011
was used for neutron energy spectrum measurements. 2270200100012
INC-SOURCE (P-LI7) Protons with energies of 20, 25, 30, 35 and 2270200100013
40 MeV bombarded a 99.98% 7Li-enriched lithium target 2270200100014
(2 mm thick) that backed by 12-mm-thick graphite. 2270200100015
INC-SPECT The neutron spectra at 0 degr. were measured at an 2270200100016
azimuthally varying field cyclotron with TOF 2270200100017
method using a 127-mm-diam. x 127mm-long NE213 liquid 2270200100018

METHOD (ACTIV,TOF) The samples were irradiated for 1 h, 2270200100026
sequentially except the carbon sample, which was 2270200100027
irradiated for 10 min. 2270200100028
DETECTOR (GE-IN) Two high-purity Ge detectors (18% and 13% 2270200100029
relative efficien.) were used for gamma-ray spectrum. 2270200100030
