Abstract

The differential cross section for the /sup 40/Ca(..gamma..,p/sub 0/) /sup 39/K process has been measured in the energy range E/sub ..gamma../ = 100-300 MeV at laboratory angles of 45/sup 0/, 90/sup 0/, and 135/sup 0/. The cross section for the (..gamma..,p) reaction leaving /sup 39/K in its ground state was extracted from the tip region of the proton spectra measured at a series of bremsstrahlung endpoint energies. The data are compared with a distorted-wave impulse-approximation calculation based on a direct, single-particle knockout mechanism.

/sup 16/O(. gamma. ,p)/sup 15/N reaction for E/sub. gamma. / = 100--400 MeV

Journal Article Leitch, M J ; Matthews, J L ; Sapp, W W ; ... - Phys. Rev. C; (United States)

The differential cross section for the /sup 16/O(..gamma..,p)/sup 15/N process has been measured in the energy range E/sub ..gamma../ = 100--400 MeV at laboratory angles of 45/sup 0/, 90/sup 0/, and 135/sup 0/. The cross sections for the (..gamma..,p) reaction leaving /sup 15/N in its ground state, in its first and second excited states at E/sub x/roughly-equal5.3 MeV, and in its third excited state at E/sub x/ = 6.3 MeV were extracted from the tip region of the proton spectra measured at a series of bremsstrahlung end point energies.

Nuclear structure and reaction mechanism studies from (p vector,pn) reactions on light nuclei and from the /sup 39/K(p,n)/sup 39/Ca and and /sup 15/N(p,n)/sup 15/O reactions

Thesis/Dissertation Pairsuwan, W

Triply-differential cross sections and analyzing powers for the /sup 2/H(p vector,pn)/sup 1/H and /sup 16/O(p vector, pn)/sup 15/O reactions were measured at several coplanar angle pairs with a 200 MeC polarized proton beam. Neutron separation-energy resolutions vary between 3-4 MeV for both targets. The data for both reactions were analyzed in the framework of the impulse approximation. The cross-section data for both reactions are in good agreement with the impulse-approximation calculations, and extracted spectroscopic factors are reasonable. The deuterium analyzing powers at small momentum transfers are in good agreement with plane-wave impulse approximation calculations. However, the oxygen analyzing powers aremore »« less
Excitation of giant resonances in the [sup 40]Ca([ital e],[ital e][prime][ital n])[sup 39]Ca reaction

Journal Article Takakuwa, C ; Saito, T ; Suzuki, S ; ... - Physical Review, C (Nuclear Physics); (United States)

Decay neutrons from the [sup 40]Ca([ital e],[ital e][prime][ital n])[sup 39]Ca reaction were studied in the giant resonance region. The cross sections and angular distributions, separated for [ital n][sub 0] and [ital n][sub 1] decays, were obtained for excitation energies between 19 and 27 MeV, at the effective momentum transfer of 0.35 fm[sup [minus]1]. Legendre polynomial coefficients obtained from fitting the data are compared with those from the ([ital e],[ital e][prime][ital p]) reaction. In the energy range 19--21 MeV, the interference coefficients [ital b][sub 1] and [ital b][sub 3] for the ground state transition are in agreement, but the noninterference coefficientmore »« less

Neutron knockout reactions from /sup 40/Ca and /sup 48/Ca

Thesis/Dissertation Ahmad, M

The reactions /sup 40/Ca(p,pn)/sup 39/Ca and /sup 48/Ca(p,pn)/sup 47/Ca at 149.5 MeV were studied at the Indiana University Cylcotron Facility in coplanar geometries with (theta/sub p/, theta/sub n/) = (44.3/sup 0/, 36.1/sup 0/) and (47.3/sup 0/, 36.1/sup 0/), respectively. An overall separation-energy resolution of about 1 MeV was achieved. The analysis of the (p-n) coincidence data was performed within the framework of the distorted-wave impulse approximation (DWIA). Spectroscopic factors (C/sup 2/S) were extracted for neutron-hole states: C/sup 2/S = 1.90 +/- 0.20 for /sup 40/Ca (2s/sub 1/2/; C/sup 2/S = 8 for /sup 48/Ca (1f/sub 7/2/; C/sup 2/S = 1.3more »« less
Short-range, high-momentum effects in the reaction /sup 16/O(. gamma. ,p/sub 0/) for E/sub. gamma. / = 100--300 MeV

Journal Article Matthews, J L ; Bertozzi, W ; Leitch, M J ; ... - Phys. Rev. Lett.; (United States)

The /sup 16/O(..gamma..,p/sub 0/) cross section has been measured for a series of photon energies between 100 and 300 MeV at proton angles of 45/sup 0/, 90/sup 0/, and 135/sup 0/. Above 250 MeV, the results exceed simple shell-model predictions by several orders of magnitude. The data are compared with a calculation which involves ..delta.. excitation in an intermediate state.
