The fixed price for a traditional Hawken rifle was $22.50 - $25.00. Several of the fine engraved Hawken rifles sold for $38 between 1837-1842. A .70 caliber Hawken rifle, the largest caliber example known, that was once owned by Theodore Roosevelt and is set for auction in May of 2024 has an estimated auction value of US$55,000 to US$85,000.

Theodore Lyman IV (/ ˈ l aɪ m ən /; November 23, 1874 – October 11, 1954) was an American physicist and spectroscopist, born in Boston. He graduated from Harvard in 1897, from which he also received his Ph.D. in 1900.
Cimarron Firearms began in 1977 as a muzzle loading shop and sporting goods store in Houston, Texas, known as "Bigfoot". Mike Harvey, who owned the shop, ordered plans for a Hawken rifle from a museum and built his first replica from scratch. As the economy worsened due to the early 1980s oil depression in Texas, Harvey sought to diversify his ...
The Lyman Series. The Lyman limit is at the wavelength of 91.2 nm (912 Å), corresponding to a frequency of 3.29 million GHz and a photon energy of 13.6 eV. [3] LyC energies are mostly in the ultraviolet C portion of the electromagnetic spectrum (see Lyman series).
The transitions are named sequentially by Greek letters: from n = 2 to n = 1 is called Lyman-alpha, 3 to 1 is Lyman-beta, 4 to 1 is Lyman-gamma, and so on. The series is named after its discoverer, Theodore Lyman. The greater the difference in the principal quantum numbers, the higher the energy of the electromagnetic emission.
The Lyman Laboratory of Physics (named for the physicist Theodore Lyman) is a building at Harvard University located between the Jefferson and Cruft Laboratories in the North Yard. [1] It was built in the early 1930s, to a design by Coolidge, Shepley, Bulfinch and Abbott [ 2 ]
In reference to the figure shown, Lyman-Werner photons are emitted as described below: A hydrogen molecule can absorb a far-ultraviolet photon (11.2 eV < energy of the photon < 13.6 eV) and make a transition from the ground electronic state X to excited state B (Lyman) or C (Werner). Radiative decay occurs rapidly.
In physics and chemistry, the Lyman limit is the short-wavelength end of the Lyman series of hydrogen emission lines at 91.13 nm (911.3 Å). The associated photon energy, 13.6 eV, corresponds to the energy required for an electron in the hydrogen ground state to escape from the electric potential barrier that originally confined it, thus creating a hydrogen ion.
