Advancing Precision Particle Background Estimation for Future X-ray Missions: Correlated Variability between AMS and Chandra/XMM-Newton

Posted by dbos MIT

Kavli Affiliate: Eric D. Miller | First 5 Authors: Arnab Sarkar, Catherine E. Grant, Eric D. Miller, Mark Bautz, Benjamin Schneider | Summary: Galactic cosmic ray (GCR) particles have a significant impact on the particle-induced background of X-ray observatories, and their flux exhibits substantial temporal variability, potentially influencing background levels. In this study, we present […]

Measurement of cesium $8P_{J}{rightarrow}$ $6P_{J’}$ electric quadrupole transition probabilities using fluorescence spectroscopy

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Yuki Miyamoto, Hideaki Hara, Minoru Tanaka, Motomichi Tashiro | Summary: Fluorescence spectra of the $8P_{J}{rightarrow}$ $6P_{J’}$ ($J$ and $J’$ = 3/2, 1/2) electric quadrupole transition of cesium atoms have been observed with a heated cesium vapor cell. We determined the ratio of the transition probabilities […]
