The robust (spin and isospin zero) α-particle remains one of the best projectiles to probe the nuclear isoscalar excitations. In the present work, a microscopic folding model analysis of the α+12 C inelastic scattering to the 2+ (4.44 MeV), 0+ (7.65 MeV), 3- (9.64 MeV), 0+ (10.3 MeV) and 1- (10.84 MeV) states in 12 C has been performed using the 3-α resonating group method wave functions. The isoscalar transition strengths of these states were carefully studied based on the coupled-channel analysis using the microscopic folded form factors. A correlation between the weak binding and/or short lifetime of the excited state and absorption in the exit channel of inelastic scattering has been established.

A form for the isospin coupling potential is derived using a particle–hole model and a coupled-channel treatment of the isobaric analogue resonance. It is well suited for numerical investigations. Comparison with the phenomenological approach shows that the present treatment provides interesting insights into the real and imaginary components of this potential.

Color Channels

A transformation table between physical bases including hidden color channels and symmetry bases for nonstrange six-quark systems is provided by using fractional parentage expansion method. By solving a coupled-channel equation, in the framework of the resonating group method (RGM), the effect of hidden color channels to all nonstrange six-quark systems is examined. It is shown that the overall effects from hidden color channels would reduce the energies of systems. For ΔΔ systems, the greatest decrease is about 20 MeV. Effects of hidden color on the masses of NN systems have been found to be about 1 MeV. However, we should emphasize that such a minor change for NN system is not negligible. We also give the most favorable hidden color channels for NN system.

We study 17 O and 18 O nuclei by using the core +n(+n) model. We perform the coupled-channel and the resonating group method (RGM) calculations not only for bound states but also for resonant states of 17 O . We obtain the state dependent core-n folding potential and reasonable single-particle energy (SPE) in the 16 O core. By using the same interaction for 17 O , we study 18 O in the core +n+n system.

Obvious Reason

In the 1940's and 1950's electron microscopy conferences were attended with everybody interested in learning about the latest technical developments for one very obvious reason. There was the electron microscope with its outstanding performance but nobody could make very much use of it because we were lacking proper techniques to prepare biological specimens. The development of the thin sectioning technique with its perfectioning in 1952 changed the situation and systematic analysis of the structure of cells could now be pursued. Since then electron microscopists have in general become satisfied with the level of resolution at which cellular structures can be analyzed when applying this technique. There has been little interest in trying to push the limit of resolution closer to that determined by the resolving power of the electron microscope.

Rattlesnake Venom

In the United States the major health problem resulting from snakebite poisoning is local tissue damage, i.e. hemorrhage and myonecrosis. Since commercial antivenin does not usually prevent such damage to tissue, a more effective treatment of snakebite-induced myonecrosis is needed. To aid in the development of such a treatment the pathogenesis of myonecrosis induced by a pure component of rattlesnake venom was studied at the electron microscopic level.The pure component, a small (4,300 mol. wt.), basic (isoelectric point of 9.6) protein, was isolated from crude prairie rattlesnake (Crotalus viridis viridis) venom by gel filtration (Sephadex G-50) followed by cation exchange chromatography (Sephadex C-25), and shown to be pure by electrophoresis. Selection of the myotoxic component was based on light microscopic observations of injected mouse muscle.
