The CFBS Experiment

Introduction

In a physical system as complex as the atomic nucleus, empirical measurements provide direction and crucial tests for various nuclear structure theories and models. For this purpose, optical spectroscopy of atomic electron orbitals has been used to probe atomic nuclear structure for over a century. Its most successful modern incarnation is collinear laser spectroscopy...

Theory

The hyperfine splitting of atomic energy levels—so named because it occurs on a scale several orders of magnitude smaller (μeV-meV) than that of the “fine structure” spin-orbital interaction— is due to perturbations of the orbitals of atomic orbitals caused by interactions with the internal structure of the nucleus...

Experimental Setup

The short-lived isotopes to be studied in the CFBS experiment are produced by TRIUMF's Isotope Separator and Accelerator (ISAC) facility. A primary proton beam of 500 MeV from TRIUMF's cyclotron is collided with a stationary target, producing exotic nuclei through spallation, fragmentation and fission reactions...
