Summary
This textbook, co-edited by Emilio G. Segrè, presents the state of experimental nuclear physics in the early 1950s. Its central thesis is to provide a comprehensive and practical guide to the experimental techniques and foundational discoveries driving the field at that time, bridging theoretical understanding with hands-on laboratory methods. The book details crucial experimental setups and methodologies, including the use of particle accelerators, detection equipment, and methods for analyzing nuclear reactions and properties. Readers gain a detailed understanding of the experimental basis for key nuclear phenomena and the challenges and innovations of early nuclear research.
The text focuses on established experimental procedures and their application to understanding nuclear structure, radioactivity, and nuclear forces. It emphasizes the importance of precise measurement and the development of sophisticated instrumentation. Key takeaway for readers is a thorough grounding in the practical aspects of experimental nuclear physics, equipping them with the knowledge to replicate or understand the experiments that shaped the field, fostering an appreciation for the empirical foundations of nuclear science.

Key concepts
- Scintillation counters — Devices used to detect and measure ionizing radiation by observing the light flashes produced when radiation interacts with a scintillator material.
- Cloud chambers — Apparatus for detecting charged particles by observing the trails of condensation left by the particles as they pass through a supersaturated vapor.
- Nuclear emulsions — Photographic plates treated with silver halides, used to record the tracks of charged particles, allowing for detailed study of their trajectories and interactions.
- Cyclotron — An early type of particle accelerator that uses a magnetic field to bend charged particles in a spiral path, accelerating them to high energies.
- Gamma ray spectroscopy — The study of gamma rays emitted from radioactive decay or nuclear reactions to determine the energy levels and properties of atomic nuclei.
