Preliminary Results

An inexpensive and convenient source of cadmium resonance radiation (λ 3261) of high intensity has been developed. This should make possible more extended studies of cadmium photosensitized reactions. Some preliminary results on the reaction between hydrogen and ethylene are reported.

Good Agreement

One of the most studied case to explore the evolution of shell closures far from stability is the doubly-magic and self-conjugated 100Sn nucleus. Information on its doubly-magic nature can be extracted fromthe systematic study of the tin isotopic chain. In this context, the lifetimes of the neutron deficient 105Sn have been investigated with the coincidence Recoil Distance Doppler Shift (RDDS) technique throughthe reaction 50Cr(58Ni,2pn)105Sn. Preliminary results concerning the lifetimesof 105In excited states are in good agreement with the adopted lifetimes, demonstrating the feasibility to extract lifetimes with this experimental technique.

Preliminary Results

An experimental technique has been developed to measure changes in vascular permeability caused by thermal trauma to the microvascular bed of the hamster cheek pouch. A solution of flourescein isothiocyanate (FITC) conjugated dextran was injected directly into the circulatory system. Subsequent leakage of dye from vessels into the extravascular space was directly observed by light microscopy and recorded by sequential photography. Individual frames of the filmed record of the trauma and post-trauma process were digitized and analyzed by computer. A point-by-point densitometric evaluation of the digitized image provides a measure of extravascular accumulation of dye-tagged dextran. Preliminary results indicate that preburn treatment with large doses of heparin yields a significant reduction in burn-induced edema.
