Pressure dependence of the Mg 3 s 4 s 3 S 1 → 3 s 3 p 3 P 0 , 1 , 2 transition in superfluid 4
نویسنده
چکیده
The pressure shifts of the 3s4sS1 → 3s3p P0,1,2 transition of magnesium atoms immersed in superfluid helium have been measured at (1.3± 0.1 )K between saturated vapour pressure and 24 bar. The wavelength is blue shifted linearly by (0.07 ± 0.01) nm bar . This value can be satisfactorily described in the framework of the standard bubble model. PACS. 67.40.Yv Impurities and other defects – 32.50+d Atomic fluorescence, phosphorescence – 32.70.Fw Line shapes, widths and shifts

The theory of the thermal hydrodynamic fluctuations in bounded systems has been developed only for non-superfluid liquids on the base of the linearized Navier-Stokes equations [1]. However, the study of effect of confined geometry on correlation functions of superfluid liquid is important for explanation of experiments in which capillaries, pores, dense suspensions and other objects are probed ...
متن کاملAdaptation to various sources of dietary sulfur by ruminants.
The objective of these experiments was to determine adaptation by ruminants to dietary sulfur. In Exp. 1, lambs (n = 54; BW = 33.6 ± 0.4 kg) were allotted to 3 treatments: 1) 0% added dietary S (0%S), 2) 0.2% added dietary S (0.2%S), or 3) 0.4% added dietary S (0.4%S). Sulfur was added to the diet as Na(2)SO(4). Lambs fed the 0.2%S and 0.4%S diets had greater (P < 0.01) ADG and G:F compared to ...

Theophylline choline 600 mg was given as a single oral dose to nine patients in chronic left ventricular failure due to myocardial dysfunction. Cardiac output, left ventricular filling pressure (LVFP) and right atrial pressure (RAP) were measured with a pulmonary artery thermodilution catheter for the following 3 hr. Continuous recordings of cardiac rhythm were made throughout the study. Mean c...

In the framework of the 3 P 0 meson decay model, the strong decays of the 3 1 S 0 and 4 1 S 0 s¯ s states are investigated. It is found that in the presence of the initial state mass being 2.24 GeV, the total widths of the 3 1 S 0 and 4 1 S 0 s¯ s states are about 438 MeV and 125 MeV, respectively. Also, when the initial state mass varies from 2220 to 2400 MeV, the total width of the 4 1 S 0 s¯...
