We recently demonstrated the ability of semiconductor quantum dots to convert alpha radiation into visible photons. In this letter, we report on the scintillation of quantum dots under gamma irradiation and compare the energy resolution of the 59 keV line of americium-241 obtained with our quantum dot-glass nanocomposite to that of a standard sodium iodide scintillator. A factor 2 improvement is demonstrated experimentally and interpreted theoretically using a combination of energy-loss and photon-transport models.
Four new superdeformed bands have been observed in ,94 T1, in addition to the two already reported. These six bands consist of three signature-partner pairs, whose energies and spacings resemble closely those in the two superdeformed bands recently reported in 193 T1. The transition-energy similarities and angular momentum alignments of these bands are discussed.
It can be concluded that XPYS-HEG is effective and safe for the treatment of people with fatigue-predominant subhealth due to liver-qi stagnation and spleen-qi deficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
