Effect of Spherical Indenter Radius on Hardness and Extraction Mechanical Property of RAFM Steel under Ion Irradiation

Yuanzineng kexue jishu, 2023
Currently, ion irradiation is commonly used to simulate neutron irradiation under specific conditions. Additionally, the nanoindentation testing system is extensively utilized for measuring the microscopic mechanical properties of materials that have been subjected to ion irradiation. One disadvantage of ion irradiation is its limited penetration depth,

A search for starlight reflected from HD 75289 b

, 2003
We have used a doppler tomographic analysis to conduct a deep search for the starlight reflected from the planetary companion to HD 75289. In 4 nights on VLT2/UVES in January 2003, we obtained 684 high resolution echelle spectra with a total integration ...

Measurement of the Radius of Neutron Stars with High S/N Quiescent Low-mass X-ray Binaries in Globular Clusters

, 2013
This paper presents the measurement of the neutron star (NS) radius using the thermal spectra from quiescent low-mass X-ray binaries (qLMXBs) inside globular clusters (GCs). Recent observations of NSs have presented evidence that cold ultra dense matter -
