The parity nonconserving longitudinal analyzing power [ital P] was measured for the [ital E][sub [ital n]]=0.88 eV neutron resonance in [sup 81]Br. The value of [ital P]=+1.77[plus minus]0.33 %; the sign is determined relative to the 0.73-eV resonanc

Cross sections were measured for /sup 12/C( p,n)/sup 12/N reaction at 99.1 MeV for nine laboratory angles between 0/sup 0/ and 48.5/sup 0/. Two detector stations were used: one at 68.0 m was for angles between 0/sup 0/ and 24.5/sup 0/, the other at 7

We present the ratio of experimental 0/sup 0/ (p,n) cross sections with the measured B(M1) values for transitions in several nuclei. Taking the strong spin-flip transition in /sup 12/C for normalization, we find overall good agreement with shell-mode

We measured the energy spectra and yields of neutrons above 1.2 MeV from nuclear capture of negative pions slowing down and stopping in C, N, O, Al, Cu, Ta, and Pb targets. Each neutron spectrum was decomposed into an evaporation portion and a direct

The 14 C(p, α) 11 B pickup reaction has been studied at a proton energy of 41.9 MeV. Differential cross sections to the ground state and 13 excited states (including members of the isospin T = 3 2 multiplet) were measured from 10° to 155° (lab). T

Cross sections for the 12 C(p, n) reaction to the ground and 0.96 MeV states of 12 N at proton energies of 61.9 MeV and 119.8 MeV amd compared with 12 C(p, p') cross sections to the analog states in 12 C at proton energies of 61.8 MeV and 122 MeV. Th

Neutron spectra from the reaction $^{48}\mathrm{Ca}$($p$,$n$) $^{48}\mathrm{Sc}$ at 160 MeV reveal a prominent narrow peak at ${E}_{x}=16.8$ MeV. This state is interpreted as a spin-flip isovector giant resonance; it carries a significant fraction of

Angular correlation measurements have been made between the deuterons and the 12 C g.s. product nuclei in the reaction 13 C ( p,d ) 12 C ∗ (15.11 MeV , 1 + )(→ 120 C g.s. + γ) at deuteron scattering angles of 40°, 50°, 60°, and 75°, and a pr
