In the 1930s and 1940s, American atomic physicists developed an identity akin to those ethnic identities developed by Chicanos and African Americans in the 1960s. Tremendous successes in high-energy physics put these American physicists at the pinnacle of science worldwide. Luis W. Alvarez was one of the central figures in this rise, was central to the development of “Big Science,” and won the Nobel Prize in 1968. However, historians have largely ignored him. Through Alvarez we see that American atomic physicists before the 1930s lacked an identity. Alvarez witnessed the growth of his field and was an early advocate for an identity for American atomic physicists. Using identity politics as a theme, we find five stories centered on Alvarez that illustrate this emerging self-image. Alvarez’s autobiography demonstrates his interest in preserving the history of physics and establishing his place in it. A textbook draft that Alvarez abandoned in 1952 further illustrates his early interest in the history of physics then absent in physics textbooks and an early interest in mythology and heroes. Alvarez’s work outside of physics helps define the boundaries of this newly self-identifying group as he conquered fields like forensics and pyramidology, as well as famously proposing the theory that an asteroid killed the dinosaurs. A collection of letters from cranks helps us demarcate science from non-science and thus define the boundaries of science. Finally, Alvarez’s identity as a physicist is contrasted with another category of identity, his ethnic identity. Alvarez was a white man with a Hispanic name, which provides us with the rare case of a white man discussing his whiteness with would-be biographers who wanted to frame him as a “Chicano physicist.” Altogether, Alvarez would, much more than any physicist in his generation, promoted and exemplified an identity as an American atomic physicist while rejecting other identities. / text

>Magister Scientiae - MSc / Physics is the study of natural phenomena. Nuclear physicists have since the discovery of the nucleus been working on understanding its dynamics. The nuclear chart, analogous to the periodic table of elements, is illustrated in Fig. 1.1 and color coded according to decay modes. Several theoretical models, based on various hypothesis, have been developed during the years in order to understand nuclear phenomena such as nucleon-nucleon (n-n) interactions, binding energies, radii, excited states, etc. Unfortunately, no-unique model is actually able to grasp all nuclear phenomena at the desired level of accuracy. Among the di erent models, we notice that two distinct hypotheses can be used to describe nuclear properties. Firstly, the independent particle shell model (IPSM) + the n-n residual interaction, which assumes that a nucleon moves independently in a potential generated by other nucleons. Secondly, the macroscopic models, where a nucleus is considered as a whole, i.e. neutrons and protons behave cooperatively and are mutually coupled to each other; highlighting the short-ranged character of the nuclear force. The liquid-drop model is an example of such macroscopic models. Re nement of these models is dependent on experimental observations that are better detailed for nuclei along the line of - stability, making up a small fraction of the known isotopes, as shown in Fig. 1.1. In practice, various techniques for studying exotic nuclei up to neutron and proton drip-lines have been devised, including the use of radioactive ion beams. However, the main challenges are the synthesization and short lived periods of these exotic nuclei resulting in insu cient data collection from which the characteristics and structural information are extracted. In general, nuclei have unique structures represented by a particular con guration as given by the shell model (SM). These structures impact a number of physical quantities, e.g. transition probabilities, cross sections and photon-strength functions. Experimental methods such as Coulomb excitation or electromagnetic radiation are used to probe these structures without invoking the nuclear force.
