How many protons are there in the nucleus of an oxygen atom? How strong is metallic hydrogen? Which atom has the smallest number of neutrons? How many protons are in an atom of hassium? What is the atomic number of a neutron? What is the Rutherford model of the atom?
摘要: Previously, it is proposed a method for determining the diameter of non-rigid stator rings of GTE compressor in case of control using coordinate-measuring machine. In this study, the mathematical model is tried out in several areas.关键词:...
BORON COATED STRAW NEUTRON DETECTOR A neutron detector technology based on 10B thin film conversion of neutrons and detection of neutron capture reaction products in a counter gas within a thin straw tube detector body is described. This neutron detector is base... LACY Jeffrey Linn - US 被引量...
The diameters of stars range from several hundreds of millions of kilometers for supergiants through about one million km for the Sun down to a few thousand km for white dwarfs and about ten km for neutron stars. For convenience the diameter or radius is usually expressed in terms of the ...
While the probable mass of the compact objects in this system is of the order of 10 solar masses, rigorous lower limits are as low as 3 solar masses (possibly even lower), marginally consistent with the maximum theoretically predicted mass of a neutron star. Even better evidence for a ...
The incident-neutron energy is optimized so that a linear and flow-regime-independent relationship between the void fraction and the neutron-detector response is obtained. The optimum energy is obtained by controlled moderation of the energy spectrum of the isotopic source. The detector and pipe are...
Comparison of neutron probe count rate ratios measured at 10 cm depth, with bulk soil water contents measured 3鈥 5m away from the access tubes, confirmed that in swelling/ shrinking clay soils, recharge may be over estimated. This is due... NJ Jarvis,PB Leeds-Harrison - 《European Journal...
The approximate radius of a neutron is 1.5 x 10-15 m, and the mass is 1.675 x 10-27 kg. Calculate the density of a neutron. V = (4/3)pir3 for a sphere. What is the volume of a cylinder of iron that has a length of 13.87 cm and a diameter of 2.36 cm? The densi...

Fast and accurate waveform models are necessary for measuring the properties of inspiraling binary neutron star systems such as GW170817. We present a frequency-domain surrogate version of the aligned-spin binary neutron star waveform mo... Lackey, Benjamin D,M Pürrer,A Taracchini,... 被引量...
