Observation of the ultra-violet photon emission from nuclei using the nuclear resonant scattering method
Optical transitions in the infrared-ultraviolet region are generally able to be controlled by coherent laser light. This realizes better energy resolution and advanced quantum coherent control than other energy regions. The quantum control is utilized to atomic or molecular phenomena today and is not utilized to nuclei so far.
"Thorium-229" is known as a unique candidate that can be quantum-controlled by coherent laser. The first excited state of the Thorium-229 nucleus has the lowest excite energy among all known nuclides, and the energy value may be around the ultraviolet region. My research aims to observe the ultraviolet photon emission from the first excited state of Thorium-229 nuclei and measure its energy accurately enough to utilize the laser technique. This is the first step towards the quantum coherent control on nuclei.
