Better measurements and improved theory are stimulating increased attention to processes in which photons eject electrons from the atoms in which they originate. Experts now concentrate on such matters as spins, parities, angular correlations and oriented nuclei.
INTERNAL CONVERSION—a process whereby an excited nucleus interacts directly with an orbital electron, imparting its excitation energy to the electron—has been intensively studied in the past few years. Experimental measurements have included K and L conversion coefficients, L and M subshell conversion‐intensity ratios, and K‐, L‐ and M‐shell particle parameters (factors relating angular distributions of conversion electrons to those of corresponding gamma rays).

The Eisenhower administration dismissed the director of the National Bureau of Standards in 1953. Suspecting political interference with the agency’s research, scientists fought back—and won.
Alternative undergraduate physics courses expand access to students and address socioeconomic barriers that prevent many of them from entering physics and engineering fields. The courses also help all students develop quantitative skills.
Defying the often-perceived incompatibility between the two subjects, some physicists are using poetry to communicate science and to explore the human side of their work.
