Mössbauer study of fired Lishan clay and terra-cotta warriors and horses of Qin dynasty (221 B.C.)

The sherds of terra-cotta warriors and horses and Lishan clay were characterized by Mossbauer spectroscopy, XRD, XRF, NAA, thermal and chemical analyses. Lishan clay was testified as the original material of terracotta warriors and horses, the kilning of these warriors and horses was first carried out in an oxidizing atmosphere, and then changed to a predominantly reducing atmosphere. With refiring experiments, the temperatures of Q3 and Q4 samples were determined to be 830±50 and 980±50°C respectively. Transformations of Lishan clay were determined by firing in oxidizing and reducing atmospheres. The Mossbauer parameters of Lishan clay, which was taken after 2–24h firing, were changing up to 12h.

Population transfer in multilevel system through modified stimulated Raman adiabatic passage

Stimulated Raman adiabatic passage (STIRAP) has been successfully extended to multilevel system. During the STIRAP process, the intermediate levels have notable population which is detrimental if these levels could decay to other levels through spontaneous emission. This paper proposes a novel method to reduce the intermediate level population during the STIRAP process. A complete population transfer can be achieved in this modified STIRAP even if the intermediate level decays to other levels.
