M047300100003 AUTHOR (M.N.Martins,E.Hayward,G.Lamaze,X.K.Maruyama, M047300100004 F.J.Schima,E.Wolynec) M047300100005 REFERENCE (J,PR/C,30,1855,1984) M047300100006 INSTITUTE (1USANIS) M047300100007 METHOD (ACTIV) Measuring the activity induced in Cu-63 by M047300100008 electrodisintegration. M047300100009 SAMPLE The target consisted of 99% enriched Cu-63 foils M047300100010 approximately 5 mg/cm**2 in NIS experiments and of M047300100011 99.9% enriched Cu-63 foils 10.0 (0.2) mg/cm**2 in M047300100012 USP experiments. M047300100013 PART-DET (B+) M047300100014 ANALYSIS The data from induced activity were acquired in five M047300100015 sequential four minute counting periods. After each M047300100016 counting period, the 511 keV annihilation peak M047300100017 counting rate was determined and corrected for decay M047300100018 to the end of the irradiation and for decay within M047300100019 the counting period. Then numbers of counting were M047300100020 used to obtain the electrodisintegration cross M047300100021 section. The USP relative data were normalized to M047300100022 the NIST absolute measurements. The M047300100023 photodisintegration cross section was obtained from M047300100024 electrodisintegration cross section using the M047300100025 virtual photon spectra theory. M047300100026 CORRECTION The measured counting rates were corrected for decay M047300100027 to the end of the irradiation and for decay within M047300100028 the each of used counting four minutes period. The M047300100029 experimental electrodisintegration cross section was M047300100030 corrected for the contribution due to the M047300100031 bremsstrahlung generated in the target. The virtual M047300100032 photon spectra were corrected for nuclear size M047300100033 effects.

M047300100041 COMMENT The bremsstrahlung cross section has been studied by M047300100042 measuring the (b+) activity induced in Cu-63 by M047300100043 electrodisintegration and when thin radiators of Cu, M047300100044 Mo, Ta, and Th were placed in the electron beam just M047300100045 ahead of the target. The electron energies were M047300100046 varied from 13.5 to 60 MeV for the reaction of M047300100047 electrodisintegration and from 20 to 60 MeV for the M047300100048 radiator-in measurements; the (g,n) cross section M047300100049 for Cu-63 was determined using virtual photon M047300100050 theory; the radiator data were fitted using various M047300100051 data on bremsstrahlung cross sections.
