The electromagnetic transition strength between the two bound states were measured in the one-neutron halo nucleus 11 Be from Coulomb excitation on 196 Pt at projectile energies of 1.727 and 2.086 MeV/nucleon at TRIUMF. A B(E1) strength of 0.102(2) e 2 fm 2 , deduced from the forward-scattering data, is consistent with previous Coulomb excitation measurements at intermediate projectile energies with a model-dependent analysis.

There are cycles in the history of scientific development just as there are in the affairs of men. To keep a Society such as The American Physical Society healthy and strong in the face of these changes, we must review our objectives periodically and adjust to the demands and needs of the present. In preparing this report on the State of Physics I sought to acquire some sense of the historical development of American physics by browsing through two famous addresses given by Henry Augustus Rowland, the founder and first president of our Society.

The Chi-Nu experiment aims to accurately measure the prompt fission neutron spectrum (PFNS) for the major actinides. At the Los Alamos Neutron Science Center (LANSCE), fission can be induced using the white neutron source. Using a two arm time of flight (T.O.F) technique; Chi-Nu presents a preliminary result of the low energy component of the 235 U PFNS measured using an array of 22-Lithium glass scintillators.
