Who among the following discovered the cascading process of cosmic radiation?

Key Points

• Homi Jehangir Bhabha was an Indian nuclear physicist, known as the father of the Indian nuclear programme.
• He is credited with the discovery of the cascading process of cosmic radiation, which is also known as the Bhabha scattering.
• Bhabha's research in cosmic rays led to the development of the field of high-energy physics in India.
• He played a significant role in the establishment of the Tata Institute of Fundamental Research (TIFR) and the Atomic Energy Establishment, Trombay (which was later renamed the Bhabha Atomic Research Centre).

Additional Information

• Cosmic Radiation
  • Cosmic rays are high-energy radiation, mainly originating outside the Solar System and even from distant galaxies.
  • Upon entering the Earth's atmosphere, cosmic rays can create showers of secondary particles, including muons, pions, and electrons.
  • The study of cosmic rays has led to important discoveries in particle physics.
• Bhabha Scattering
  • Bhabha scattering is the process by which an electron and a positron scatter off each other.
  • It is named after Homi J. Bhabha who first calculated the cross-section of electron-positron scattering in 1935.
  • This work has significant implications in the field of quantum electrodynamics and particle physics.
• Bhabha Atomic Research Centre (BARC)
  • Bhabha Atomic Research Centre (BARC) is India's premier nuclear research facility based in Trombay, Mumbai.
  • Bhabha played a crucial role in its establishment, and it was renamed in his honor after his death.
  • BARC is involved in advanced research and development in the fields of nuclear science, engineering, and related areas.
