The reaction gamma p-->pi(+)K(-)K(+)n was studied at Jefferson Laboratory using a tagged photon beam with an energy range of 3-5.47 GeV. A narrow baryon state with strangeness S=+1 and mass M=1555+/-10 MeV/c(2) was observed in the nK(+) invariant mass spectrum. The peak's width is consistent with the CLAS resolution (FWHM=26 MeV/c(2)), and its statistical(More)
The dipole response of 76 34 Se in the energy range from 4 to 9 MeV has been analyzed using a (γ , γ) polarized photon scattering technique, performed at the High Intensity γ-Ray Source facility at Triangle Universities Nuclear Laboratory, to complement previous work performed using unpolarized photons. The results of this work offer both an enhanced(More)
Mothers of preterm infants are reported to experience heightened levels of psychological stress, greater than mothers of full-term infants during the neonatal period. The purpose of this study is to describe the lived experience of what it is like to be a mother of an extremely low birth-weight infant during their stay with their infants in the NICU.(More)
Two models of maternal-infant attachment, one related to full-term newborns (Goulet, Bell, St-Cyr Tribble, Paul, & Lang, 1998), and one including premature infants (Bialoskurski, Cox, & Hayes, 1999), are examined. The elements of both models are integrated into a more comprehensive model. Implicit organizational components are made explicit, and a(More)
We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for "fast" nucleons (p>250 MeV/c) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy. These fast pp and pn pairs are back to back with little momentum along the three-momentum transfer,(More)
High-sensitivity studies of E1 and M1 transitions observed in the reaction 138Ba(gamma,gamma{'}) at energies below the one-neutron separation energy have been performed using the nearly monoenergetic and 100% linearly polarized photon beams of the HIgammaS facility. The electric dipole character of the so-called "pygmy" dipole resonance was experimentally(More)
The (n, 2n) cross section of the radioactive isotope 241 Am (T 1/2 = 432.6 y) has been measured in the incident neutron energy range from 7.6 to 14.5 MeV in steps of a few MeV using the activation technique. Monoenergetic neutron beams were produced via the 2 H(d, n) 3 He reaction by bombarding a pressurized deuterium gas cell with an energetic deuteron(More)
