2021 Symmetry  
Combining with results from the β decay of 26P and its mirror nucleus 26Na, the mirror asymmetry parameter δ ( ≡ft+/ft−− 1) was determined to be 46(13)% for the transition feeding the first excited state  ...  The experiment was performed at the National Laboratory of Heavy Ion Research Facility in Lanzhou (HIRFL) to measure the β-delayed γ rays of 26P by silicon array and Clover-type high-purity Germanium (  ...  In this paper, we present the independent and rather complete results of the β-delayed γ decay of 26 P. The mirror asymmetries were discussed concerning the shell-model calculation.  ...

2016 Physical Review C  
Results: The absolute intensities of ^26P β-delayed γ-rays were determined. A total of six new β-decay branches and 15 new γ-ray lines have been observed for the first time in ^26P β-decay.  ...  Its β-delayed γ-ray emission was measured with an array of 16 high-purity germanium detectors. Positrons emitted in the decay were detected in coincidence to reduce the background.  ...  ACKNOWLEDGMENTS The authors gratefully acknowledge the contributions of the NSCL staff.

2004 European Physical Journal A  
The β-decay properties of the neutron-deficient nuclei ^25Si and ^26P have been investigated at the GANIL/LISE3 facility by means of charged-particle and γ-ray spectroscopy.  ...  A precise half-life of 43.7 (6) ms was determined for ^26P, the β- (2)p decay mode of which is described.  ...  It allowed us to measure the asymmetry parameter δ for the mirror states of the mass A=25 and A=26 nuclei.  ...

Chip-scale optical frequency comb sources for terabit communications

Pablo Marin-Palomo
The number of devices connected to the internet and the required data transmission speeds are increasing exponentially.  ...  With typical distances from a few kilometers to 100 km, these links require the use of a high number of WDM channels. The associated transceivers should have low cost and footprint.  ...  Acknowledgments This dissertation was written during my doctoral studies at the Institute of Photonics and Quantum Electronics (IPQ) at the Karlsruhe Institute of Technology  ...
