Investigation of the Kπ = 8− Isomers in N=74 Isotones on Beam of the Warsaw Cyclotron
نویسنده
چکیده
The decay of the K= 8− isomers in Ce and Nd have been investigated on the beam of the Warsaw Cyclotron using OSIRIS array. Reactions Sn(O,4n)Ce and Sn(Ne,4n)Nd were used. Two new decay paths have been found in the deexcitation of the 8− isomer in Ce. The hindrance factors for the E1, M2 and E3 transitions deexciting the isomer have been determined. Similar E3 decay of the 410 μs isomeric state in Nd has not been observed in our experiment but nevertheless the reduced hindrance factor f3 ≥ 9 was determined. The decay properties of the 8− isomers in the N=74 isotones are discussed.

Tautomeric equilibria for ionized oxamic acid - inhibitor of LDH
Amide-iminol tautomerism was studied for ionized oxamic acid (OA+•) in the gas phase using theDFT method with the UB3LYP functional and various basis sets {6-31++G(d,p), 6-311+G(d,p), and augcc-pVDZ}. Among twenty tautomers-rotamers possible for OA+•, eleven isomers were found to bethermodynamically stable. Similarly as for the neutral molecule, ionization (OA → OA+• + e) favors theamidization ...
متن کاملEffect of Filter Inhomogeneity on Deep-Bed Filtration Process – A CFD Investigation
Aerosol filtration in fibrous filters is one of the principal methods of removal of solid particles from the gas stream. The classical theory of depth filtration is based on the assumption of existing single fiber efficiency, which may be used to the recalculation of the overall efficiency of the entire filter. There are several reasons for inappropriate estimation of the single fi...

The radioisotope 67Ga (T 1/2 = 78 h) in extensively used as single photon marker for detecting the presence of malignancy and the diagnosis of inflammatory diseases. The high tumor specificity of carrier-free 67Ga make it one of the most interesting radionuclides in nuclear medicine for in vivo scanning studies. 67Ga is a cyclotron produced radioisotopes and is one of the radiopharmaceuti...
متن کاملAdjusting yield components under different levels of N applications in winter wheat
This work presents information on the patterns of yield determination by yield components as a function of the level of management of the crop. The data used for the analyses were obtained from 8 field experiments located across Poland in 2009 and 2010. 25 winter wheat cultivars were evaluated at two management levels, i.e., at a low input of nitrogen fertilisation and pesticides and at a h...
متن کاملTargetry for cyclotron production of no-carrier-added cadmium-109 from natAg(p,n)109Cd reaction
Background: Solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. Since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109Cd. To avoid cracking or peeling of the target during bombardment, it should have a level surface a...
