This equation, Bragg's law, describes the condition on θ for constructive interference. [12] A map of the intensities of the scattered waves as a function of their angle is called a diffraction pattern. Strong intensities known as Bragg peaks are obtained in the diffraction pattern when the scattering angles satisfy Bragg condition.
Scattering also includes the interaction of billiard balls on a table, the Rutherford scattering (or angle change) of alpha particles by gold nuclei, the Bragg scattering (or diffraction) of electrons and X-rays by a cluster of atoms, and the inelastic scattering of a fission fragment as it traverses a thin foil.

Emperor Quang Trung (Vietnamese: [kwāːŋ ʈūŋm]; chữ Hán: 光中, 1753 – 16 September 1792) or Nguyễn Huệ (chữ Hán: 阮惠), also known as Nguyễn Quang Bình (chữ Hán: 阮光平), or Hồ Thơm (chữ Hán: 胡𦹳) was the second emperor of the Tây Sơn dynasty, reigning from 1788 until 1792. [2]
During the existence of the General Headquarters of the Vietnam People's Army (Bộ Tổng tư lệnh Quân đội Nhân dân Việt Nam), which had been the supreme commanding organ of the armed forces from 1946 to 1975, the General Staff was directly under the General Headquarters and acted as staff of the General Headquarters according to ...
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.
Phạm Hùng, Secretary of the Central Office of South Vietnam (COSVN), outlined the requirements about the ordered anthem: [1] [2] The anthem's targets were all of the population of South Vietnam. The anthem had to call for the armed insurrection against the US-backed Saigon regime and the unification of Vietnam as a whole.
It may be considered Vietnam's national card game, and is common in communities where Vietnamese migration has occurred. It is also played in the United States, sometimes under the names Viet Cong , [ 2 ] VC , [ 2 ] Thirteen (which is also the common English name in Australia's Vietnamese migrant community), [ 2 ] Killer , [ 2 ] or 2’s .
