Magnetic and electrical property study on La-diluted Kondo lattice CeIn3
Understanding the Kondo lattice system is challenging because of the complexity of the Ruderman–Kittel–Kasuya–Yosida (RKKY) interactions and the interplay of the Kondo effect with the crystal electric field (C...

Storage rings in Korea as synchrotron radiation source
Remarkable progress has been made in photon beam brightness from storage rings. From the early 90’s, third-generation storage rings (3GSRs) have been put into operation and have provided very bright photon bea...

Feasibility Study of Upgrades to the PLS-II Storage Ring
The PLS-II is a third-generation light source; it has been operating since 2011. It has a double-bend structure with non-zero dispersion along the straight section. Here, we assess three proposed upgrades to t...

The quenching of nucleon yields in the nonmesonic weak decay of Λ -hypernuclei and the three-body weak decay process
Recent exclusive coincidence measurements of non-mesonic weak decays (NMWD) reported for the ratio of the partial decay width of neutron-induced-to-proton-induced NMWD, Γn/Γp , values of 0.45±0.11±0.03 and 0.51±0...
