Untersuchung des zerfalls von F21
Nuclear Physics (journal), 1963F/sup 21/ is produced by the F/sup 19/(t,p)F/sup 21/ reaction. It is shown conclusively that F/sup 21/ decays by BETA -branches to the 0.345and 1.73- Mev states of Ne/sup 21/ with a half life of 4.6 ction in DDT-C/ 0.3 sec. A decay scheme including spin assignments of the ground state of F/sup 21/ (5/2/sup +/) and the 0.345-Mev (5/2/sup +/) and the 1 ...

Investigation of the energy levels of F21 using the F19(t, p)F21 reaction
Nuclear Physics (journal), 1964Abstract Using the F19(t, p)F21 reaction, the energy levels of F21 up to an exitation energy of 5.9 MeV were investigated. Previously unreported levels were found at 5.35, 5.49, (5.57), 5.59, 5.79 and 5.88 MeV. The energy levels below 5.07 MeV are found to be in agreement with previous work.

F21. Electroclinical manifestations in term newborns with neonatal hypoglycemia
Clinical Neurophysiology, 2018Introduction Neonatal hypoglycemia is a relatively common event with a variable clinical presentation, ranging from asymptomatic forms to refractory status epilepticus. It may present as a primary problem or appear in the context of other conditions, such as prematurity or severe systemic disorders (sepsis, hypoxic ischemic encephalopathy ...

Some energy levels of F21 and Na25
Nuclear Physics, 1962Abstract The F19(t, p)F21 reaction has been studied by magnetic analysis and the excitation energies of 19 states have been determined. The Q-value of the reaction was measured to be 6.219±0.012 MeV which is consistent with F21 having a mass excess of −0.045±0.012 MeV. Excitation energies of 26 states of Na25 have also been measured using the Na23(t,

New DUV resist characterisation: stability to MB SEMI© F21-95 contaminants
Materials Science and Engineering: B, 2004Abstract Airborne molecular contamination (AMC) effects reveal to be more and more prominent in clean room manufacturing areas, shrinking the dimensions of electronic circuits such as the last generation of flash memory devices (0.15–0.13 μm). This work enabled us to evaluate new resist stability to specific airborne contamination class in critical ...

ИЗОТОПЫ ФТОРА F19 И F21 В МОДЕЛИ НИЛЬССОНА
Czechoslovak Journal of Physics, 1968Energy levels and electromagnetic properties of fluorin isotopes in the Nilsson's model with Coriolis mixing are investigated. Position of the F19 levels is satisfactorily explained up to the energy of 4·5 MeV. Concerning the F21 it seems that the shell model will better correspond to the F21 nucleus.

[Acylation specificity of midecamycin 3-O-acyltransferase within Streptomyces spiramyceticus F21].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2010Spiramycin and midecamycin are 16-membered macrolide antibiotics with very similar chemical structures. Spiramycin has three components, namely spiramycin I, II and III. Spiramycin II and III are, respectively, the O-acetyl and propionyl derivatives at C3-hydroxyl group of spiramycin I.
