The Bragg curve of 5.49 MeV alphas in air has its peak to the right and is skewed to the left, unlike the x-ray beam below. The Bragg peak is a pronounced peak on the Bragg curve which plots the energy loss of ionizing radiation during its travel through matter.
In X-ray crystallography, wide-angle X-ray scattering (WAXS) or wide-angle X-ray diffraction (WAXD) is the analysis of Bragg peaks scattered to wide angles, which (by Bragg's law) are caused by sub-nanometer-sized structures. [1] It is an X-ray-diffraction [2] method and commonly used to determine a range of information about crystalline materials.
Camp Bragg was a major Confederate encampment located in Ouachita (present-day Nevada) County, Arkansas, [1] [2] about 23 miles (37 km) southwest of Camden. [3] It served as Headquarters of the District of Arkansas from October 1863 until January 1864, when it was replaced by Camp Sumter, Arkansas.
There are four of these in Arkansas. The National Park Service lists these four together with the NHLs in the state, [6] The Arkansas Post National Memorial, the Fort Smith National Historic Site (shared with Oklahoma) and the Little Rock Central High School National Historic Site are also NHLs and are listed above. The remaining one is:
In order to achieve diffraction conditions, the sample under study must be precisely aligned. The contrast observed strongly depends on the exact position of the angular working point on the rocking curve of the sample, i.e. on the angular distance between the actual sample rotation position and the theoretical position of the Bragg peak.

Beginning around 11,700 B.C.E., the first indigenous people inhabited the area now known as Arkansas after crossing today's Bering Strait, formerly Beringia. [3] The first people in modern-day Arkansas likely hunted woolly mammoths by running them off cliffs or using Clovis points, and began to fish as major rivers began to thaw towards the end of the last great ice age.

The Arkansas General Assembly established the Arkansas History Commission through the Act of 1905 signed by Governor Jeff Davis on April 27. [2] Aligned with Department of Parks and Tourism since 1971, it was transferred to the Department of Arkansas Heritage on July 1, 2016, and renamed Arkansas State Archives. [3]
