  2. Isotopes of helium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_helium

    The shortest-lived isotope is 10 He with half-life ~260 yoctoseconds. 6 He beta decays with half-life 807 milliseconds. The most widely studied heavy helium isotope is 8 He. 8 He and 6 He are thought to consist of a normal 4 He nucleus surrounded by a neutron "halo" (of two neutrons in 6 He and four neutrons in 8 He).

    He 111U Propaganda designation of the He 119 He 119 Basic version, eight prototypes built. He 519 1944 high-speed bomber development, designed as a private venture by Heinkel to test radical ideas by the Günter brothers, the He 519 was designed to use the 24-cylinder Daimler-Benz DB 613, but the aircraft remained a concept and was abandoned at the end of the war.

  4. Heinkel He 177 Greif - Wikipedia

    en.wikipedia.org/wiki/Heinkel_He_177_Greif

    The He 177 V6 was the first aircraft equipped with main production type DB 606 A/B engines instead of the pre-production units, which offered a slight increase in take-off power by 100 PS to 2700 PS (2,663 hp, 1,986 kW). The He 177 V7 featured a revised nose section which, while generally following the contours of the nose sections employed by ...

    For 1956 the 265 cid V8 engine was modified to include an integral oil filter, with a range of power choices from 162 HP for the base V8 up to 240 HP for R.P.O. 411 "Super Power Pack" offered mid-year. [13] [14] [15] The average two door Bel Air in 1956 sold for $2100, which was considered a good value at the time.

  6. Helium–neon laser - Wikipedia

    en.wikipedia.org/wiki/Helium–neon_laser

    The best-known and most widely used He-Ne laser operates at a center wavelength of 632.81646 nm (in air), 632.99138 nm (vac), and frequency 473.6122 THz, [1] in the red part of the visible spectrum. Because of the mode structure of the laser cavity, the instantaneous output of a laser can be shifted by up to 500 MHz in either direction from the ...

  7. Heat capacity ratio - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity_ratio

    The above value of 1.4 is highly consistent with the measured adiabatic indices for dry air within a temperature range of 0–200 °C, exhibiting a deviation of only 0.2% (see tabulation above). For a linear triatomic molecule such as CO 2 , there are only 5 degrees of freedom (3 translations and 2 rotations), assuming vibrational modes are not ...

    Only 79 original S.E.5 aircraft had been completed prior to production settling upon an improved model, designated as the S.E.5a.The initial models of the S.E.5a differed from late production examples of the S.E.5 only in the type of engine installed – a geared 200 hp Hispano-Suiza 8b, often turning a large clockwise-rotation four-bladed propeller, replacing the 150 hp H.S. 8A model.
