Department of Physics and Astronomy

Nuclear, Astro and Particle Physics Seminars

These lectures feature speakers from around the country and globe. Each seminar lasts about an hour and takes a closer look at more specialized fields in various realms of physics and astronomy.

Many seminars will be held in a hybrid format and a recurring Zoom link is provided to access the virtual format.

The talks will be on Wednesdays at 4PM in the Rogers Room (Jones PSC 409).

Upcoming Seminar (Spring 2025):

Experimental Approaches to Understand Reaction Mechanisms Relevant to Discrete Symmetry Violation in Compound Nuclear Process

Speaker: Hirohiko M. Shimizu
Affiliation: Nagoya University
Date: Mar 19th

Abstract: 

Detailed understanding of neutron absorption reactions helps us to understand the extremely large parity violating effects and evaluate the possibility to extend to other enhancement of other symmetry breakings. Currently, the parity breaking effect is understood as a result of the interference between parity-unfavored partial amplitudes of the compound nuclear process, which is referred to as "s-p mixing". We discuss experimental approaches that simplify the compound-nucleus process and distinguish as much as possible between the entrance channel boundary, exit channel boundary, and compound-nucleus state. Critical technologies for these experiments, such as neutron and nuclear spin manipulation and neutron detection, will be overviewed.
