M049500100004 AUTHOR (T.J.BOWLES,R.J.HOLT,H.E.JACKSON,R.M.LASZEWSKI, M049500100005 R.D.MCKEOWN,A.M.NATHAN,J.R.SPECHT) M049500100006 REFERENCE (J,PR/C,24,1940,1981) M049500100007 INSTITUTE (1USAUI) M049500100008 FACILITY (MICRT,1USAUI) Electron microtron MUSL-2. M049500100009 INC-SOURCE (QMPH,TAGD) M049500100010 METHOD (EXTB) M049500100011 DETECTOR (NAICR) M049500100012 SAMPLE All of the targets used were metallic samples, except M049500100013 for Cr-52 which was in form (Cr-52)-2(O-3), and all M049500100014 except the fe were inclosed in a thin-walled lucite M049500100015 container. Typical target thickness were 2 - 4 M049500100016 g/cm**2. M049500100017 PART-DET (G) M049500100018 ANALYSIS The relation between the number of scattered photons M049500100019 detected in the nai detector and the differential M049500100020 cross section (d-sig)/(d-omega) is ns = k*(d-sig)/ M049500100021 (d-omega)*(omega-d)*ng*epsilon, where k is the M049500100022 effective number of scattering centers per unit M049500100023 area, omega-d is the solid angle substended by the M049500100024 detector, epsilon is the detector efficiency, and M049500100025 the ng is the total number of the tagged photons M049500100026 incident on the target. M049500100027 ERR-ANALYS The statistical errors are presented only. M049500100028 CORRECTION The corrections were made for background and for M049500100029 electronic interactions of the photons in the target M049500100030 material (typically about 15%). M049500100031 COMMENT Quasimonochromatic photons have been used to measure M049500100032 elastic and inelastic photon scattering cross M049500100033 sections in the giant dipole resonance region of M049500100034 Cr-52, Fe, Ni-60, Mo-92, and Mo-96 in an experiment M049500100035 in which the elastic and inelastic scattering are M049500100036 resolved. the elastic scattering cross sections show M049500100037 clear evidence for isospin splitting of the giant M049500100038 dipole resonance. the inelastic scattering to M049500100039 low-lying vibrational levels, which is a measure of M049500100040 the coupling between the giant dipole resonance and M049500100041 collective surface vibrations, is in qualitative M049500100042 agreement with the predictions of the dynamic M049500100043 collective model.
