Nuclear orientation and NMRON in rare earths

The rare-earth or lanthanoid series of elements offers a rich ground for the study of both solid-state phenomena and nuclear physics. Some systematic investigations of these elements as host materials and as impurity isotopes have been performed using the nuclear orientation methods, and more can be expected in the near future owing to recent technical developments. A review of past work in this area is given, and the outlook for future experiments is summarized. (orig.)
