Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics.

Abstract

Research into nuclear isomers can lead to the development of a gamma-ray laser (GRASER), thus opening up the perspective of quantum optical studies on high energetic gamma-radiation. The unique capabilities of novel, ultra-high intensity multi-tera- and petawatt laser facilities enable investigations into a possible direct population of nuclear isomers via hot electron plasmas. We present the theoretical rationale and review performed measurements. A new experimental strategy to find unambiguous evidence for the direct laser induced population of the short lived Ta-181m, will be discussed.
