Recoil - distance lifetime measurements of V levels
Lifetimes for a number of level. s in 4 V have been measured using the recoil-distance technique. The experimental results for the mean lifetimes are 8.8+1.4 psec for the 428keV 5+ level, 21.6+1.1 psec for the 613-keV 4+ level, 111+9 psec for the 627-keV 6+ level, 6.7+ 1.8 psec for the 1056-keV 3 level, and 6, 5+ 0.5 psec for the 1099-keV 4~ ~ level. Lifetime l.imits were measured for other lev...
متن کاملPrecision Lifetime Measurements Using the Recoil Distance Method
The recoil distance method (RDM) for the measurements of lifetimes of excited nuclear levels in the range from about 1 ps to 1000 ps is reviewed. The New Yale Plunger Device for RDM experiments is introduced and the Differential Decay Curve Method for their analysis is reviewed. Results from recent RDM experiments on SD bands in the mass-190 region, shears bands in the neutron deficient lead is...
متن کاملIntraocular Pressure Measurements by Three Different Tonometers in Children with Aphakic Glaucoma and a Thick Cornea
Background: To evaluate the agreement in intraocular pressure (IOP) measurements by Ocular Response Analyzer (ORA) and Tono-Pen XL (TXL) with the Goldmann Applanation Tonometer (GAT) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (CCT) >600 µ. Methods: Thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...
متن کاملRetrieving Nuclear Information from Protons Propagating through a Thick Target
The multiple scattering of high-energy particles in a thick target is formulated in an impact parameter representation. A formalism similar but not identical to that of Molière is obtained. We show that calculations of particle beam broadening due to multiple Coulomb scattering alone can be given in closed form. The focus of this study is on whether or not the broadening of the Coulomb angular ...
متن کاملFaraday rotation density measurements of optically thick alkali metal vapors
We investigate the measurement of alkali number densities using the Faraday rotation of linearly polarized light. We "nd that the alkali number density may be reliably extracted even in regimes of very high bu!er gas pressure, and very high alkali number density. We have directly veri"ed our results in potassium using absorption spectroscopy on the second resonance (4 SP5 P). 2001 Published by ...
