With Pyotr Kapitsa, Lev Landau, Igor Kurchatov, Abram Alikhanov and others, he laid the foundations of nuclear physics in the Soviet Union.

[1] Artem Alikhanian was born in Elizavetpol, Russian Empire, to an Armenian family of a railway engineer and homemaker.

For observation of positrons, Alikhanov, his student M. Kozodaev and Alikhanian used an original combination of a magnetic spectrometer and two contiguous Geiger-Müller counters making coincidence counts.

This work became a starting point for the application of radio engineering to experimental nuclear physics in the Soviet Union.

[3] Before World War II, they carried out fundamental investigations of beta decay, discovered the internal conversion of gamma rays and confirmed experimentally the energy conservation in positron annihilation.

In 1942, they initiated a scientific mission on Mount Aragats in order to search for the third (proton) component of cosmic rays.

After they founded a cosmic ray station on Aragats at an altitude of 3250 m, the two brothers participated in the foundation of the Armenian Academy of Sciences and established the Yerevan Physics Institute in 1943.

[13] From 1961 to 1975 he organized the world-renowned annual International Schools of High Energy Physics at Nor-Amberd, with participation of many academics and Nobel Prize laureates.
