The elastic scattering of composite projectiles by nuclei is considered in the semiclassical limit. Criteria based on this description are obtained for incident energy and angular range data necessary to eliminate discrete ambiguities optical potentials such projectiles. We demonstrate effectiveness these criteria $\ensuremath{\alpha}$-scattering data.
We report on recent $\ensuremath{\alpha}$-scattering experiments at 141.7 MeV using $^{40}\mathrm{Ca}$ and $^{90}\mathrm{Zr}$ targets. The results are compared with previous other nuclides approximately the same energy used to illustrate phenomena occurring in intermediate-energy $\ensuremath{\alpha}$ scattering which we have given name "refractive behavior." All elastic differential cross sections exhibit exponential-like falloff large angles characteristic of nuclear rainbow scattering....
The ($p, p\ensuremath{\alpha}$) reaction on $^{6}\mathrm{Li}$, $^{7}\mathrm{Li}$, $^{9}\mathrm{Be}$, and $^{12}\mathrm{C}$ has been investigated experimentally at a bombarding energy of 100 MeV. Data were obtained large number angle pairs in order to study the mechanism. data are good agreement with distorted-wave impulse-approximation calculations; unlike most analyses transfer reactions we obtain absolute $\ensuremath{\alpha}$-particle spectroscopic factors. These $1p$ shell model...
We have measured the elastic scattering from $^{28}\mathrm{Si}$ of 135.1-MeV $^{6}\mathrm{Li}$ and 186-MeV $^{12}\mathrm{C}$ ions. The shapes angular distributions resultant optical-model analyses indicate that is quite similar to light ions, while ions behave like heavier Thus there appears be a pronounced rapid transition characteristics with projectile mass.
The elastic and inelastic scattering of $\ensuremath{\alpha}$ particles by $^{58}\mathrm{Ni}$ $^{208}\mathrm{Pb}$ has been investigated at an incident energy 139 MeV. cross sections have analyzed in terms the optical model using a six-parameter Woods-Saxon potential. data for are sufficient to eliminate discrete ambiguity strength potential; single potential which fits well depth 116 MeV volume integral $\frac{J}{4A}$ 298 ${\mathrm{fm}}^{3}$. For could not be resolved. This outcome is...
We have obtained new $^{16}\mathrm{O}$ + $^{28}\mathrm{Si}$ elastic scattering data at 215.2 MeV laboratory bombarding energy which show no evidence of strong rainbow effects. found that it is possible to simultaneously fit low and high with the same energy-independent Woods-Saxon optical potential. find imaginary potential for such fits greater than or equal real in surface region a marked preference well depth about 10 MeV, as determined nuclear surface.NUCLEAR REACTIONS...
In Brief Field hospitals were deployed by the Israel Defense Forces as part of international relief efforts after major seismic events, one in Haiti (2010) and Japan (2011). The teams treated a total 44 pregnant 24 nonpregnant women performed 16 deliveries three cesarean under extreme conditions. Half all complicated preeclampsia 31% preterm (at 30–32 weeks gestation). It is imperative that obstetrician–gynecologists be included among humanitarian aid delegations sent to sites natural...
Chemical-based fluorescent sensors with the capability of long-term stability and low cost are promising agents in clinical diagnosis medical research. Measuring glucose levels inside cells their surroundings provides insight into cellular metabolic homeostasis may be employed as an indicator for potential pathological conditions. Anthracene-based diboronic acid (BA) derivatives offer a reversible covalent binding mechanism recognition, which enables robust continuous monitoring. To improve...
Summary. Late wilt of maize, caused by the fungus Harpophora maydis, is one most important fungal diseases in Egypt. The disease has also been reported from India, Hungary, Spain and Portugal. pathogen survives for long periods soil. currently controlled using maize varieties with reduced sensitivity, but virulent variants may threaten these varieties. Common symptoms have documented over 20 years Upper Galilee (northern Israel), particularly Hula Valley. Recently, prevalence increased. This...
Normalization of serum phosphorus is critical in the treatment End Stage Renal Failure patients. Aluminum or calcium based phosphate binders, while efficacious, are associated with potential adverse side effects and toxicities. We have developed RenaGel, a novel, non-absorbed hydrogel which binds dietary leading to increased fecal excretion, decreased absorption levels. In this paper, we present results from both vitro vivo studies examined efficacy novel binder.In vitro, RenaGel was...
We have cloned two cDNAs from the pituitary gland of blue gourami (Trichogaster trichopterus), coding for beta subunits gonadotropin hormones GtH-I and GtH-II. The were sequenced subjected to sequence analysis. found that deduced amino acid sequences both most similar their striped bass counterparts. shared 73% residues, GtH-II 84%. cloning has enabled us measure expression respective mRNAs in pituitaries female at different stages reproductive cycle. highest levels mRNA specimens classified...
It is shown that the fields associated with TM/sub 01/ (transverse magnetic) mode of an elliptical waveguide are qualitatively different from those which have appeared in standard literature for past 50 years, and original as plotted were also qualitative disagreement analytic expressions accompanied them. Nonetheless, cutoff frequencies given well five other modes exceedingly accurate (within roughly 1%) eccentricities large 0.75; excess 0.9, inaccuracy increases 5% to nearly 50%, depending...
Abstract
The reaction $^{6}\mathrm{Li}(\ensuremath{\alpha},2\ensuremath{\alpha})d$ was studied at 50.4, 59.0, 60.5, 70.3 and 79.6 MeV. angular distributions energy dependence of the off-energy-shell $\ensuremath{\alpha}\ensuremath{-}\ensuremath{\alpha}$ cross section were extracted compared with those for free scattering. agreement between two is excellent, as predicted by peripheral model in quasifree approximation, but approximation not precise enough.
