PURPOSE To evaluate the rate of pathologic complete response and toxicity of neoadjuvant chemoradiation for advanced T3/T4 distal rectal cancers in a randomized phase II study PATIENTS AND METHODS Patients with clinical T3/T4 distal rectal cancers were randomly assigned in a phase II study to receive combined neoadjuvant chemoradiotherapy followed by(More)
Data collection during the aerobraking period. The atmospheric density of Mars at the aerobraking altitude showed significant variation over time as well as large orbit-toorbit differences. On each orbit the density must be predicted to determine the appropriate and safe depth within the atmosphere for the aerobraking passage sufficiently in advance to(More)
The interaction of an E/A=70-MeV (7)Be beam with a Be target was used to populate levels in (6)Be following neutron knockout reactions. The three-body decay of the ground and first excited states into the α+p+p exit channel were detected in the High Resolution Array. Precise three-body correlations extracted from the experimental data allowed us to obtain(More)
Neutron elastic-scattering angular distributions were measured at beam energies of 11.9 and 16.9 MeV on 40,48 Ca targets. These data plus other elastic-scattering measurements, total and reaction cross-sections measurements, (e, e p) data, and single-particle energies for magic and doubly magic nuclei have been analyzed in the dispersive optical-model(More)
The decay of 10 C excited states to the 2p + 2α exit channel has been studied using inelastic excitation of a secondary 10 C beam. The decay sequences leading to the 2p + 2α final state are determined for the previously known levels and for a newly found level at E * = 8.4 MeV. A state at E * = 6.57 MeV is shown to undergo two-proton decay to 8 Be g.s. with(More)
