The estimated lifetime of the most prominent optical emission of
samarium from the [sup.4][G.sub.5/2] level is 0.726 ms.
The method of separating neodymium and
samarium oxides from mined raw ore, then reducing those oxides to a usable metallic element is difficult.
Government should provide incentives (tax breaks, contract preferences, and so forth) for domestic companies striving to revive REE mining, refining of neodymium or
samarium, or production of rare earth magnets.
The M1A2 Abrams tank uses
samarium cobalt magnets in its reference and navigation system.
With a 17mm diameter state of the art
Samarium Cobalt magnet, low thermal mass and an aluminium knob for easy handling, these probes will quickly and securely attach to ferrous substrates making them faster to attach and more secure than an exposed junction probe.
In contrast, the decay of
samarium (Sm), to neodymium (Nd), provides one of the best tracers for tectonic processes (e.g.
The Cobalt-Samarium (CoSm) magnet is made of iron, nickel, cobalt and rare-Earth
Samarium (Bose, 2002).
* Commonly neodymium iron boron or
samarium cobalt magnets.
Cytogen's marketed products include QUADRAMET(R) (
samarium Sm-153 lexidronam injection), PROSTASCINT(R) (capromab pendetide) kit for the preparation of Indium In-111 capromab pendetide, and SOLTAMOX(TM) (tamoxifen citrate, oral solution 10mg/5mL) in the United States.
The scientists are working with the following lanthanide oxides: lanthanum, cerium, praseodymium, neodymium,
samarium and gadolinium.
The scientists are working with seven lanthanide oxides: lanthanum, which is used in carbon lighting applications and optical glass manufacturing; cerium, used as a catalyst in sell-cleaning ovens; praseodymium, commonly used in an alloy found in lighter flints and carbon electrodes for are lighting; neodymium, used for coloring glass and ceramics and for filtering infrared radiation;
samarium, used in magnets, in alloys with cobalt, and in nuclear reactors: and gadolinium, which is also used in magnets.
