Samarium 153Sm Lexidronam

Drugs & Aging, 1997
Samarium 153Sm lexidronam is a medium energy beta-emitting radioisotope chelated to the tetraphosphate, ethylenediaminetetramethylenephosphonic acid (EDTMP). 153Sm has a physical half-life of 1.9 days. Samarium 153Sm lexidronam concentrates in bone tissue and has a metastatic lesion: normal bone ratio of 4.

The standardization of samarium-153

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1987
Samarium-153 has been standardized by 4 pi beta liquid-scintillation counting, with an uncertainty of 0.4%. The probability per decay for the 103.2-keV gamma ray was measured, using two germanium detectors, to be 0.298 +/- 0.004. The half life, based on liquid-scintillation measurements over 6.4 half lives and pressurized-ionization-chamber ...

Radioactivity of Samarium

Nature, 1932
THE discovery that the radioactivity of potassium is due to a minor isotopic constituent, suggests the idea that other common elements may also have radioactive isotopes present in small amounts. This line of thought induced us to investigate the properties of samarium and we found this element to be markedly radioactive.

Samarium Diiodide/Samarium-Mediated Deoxygenative Hydrosilylation of Ketones

The Journal of Organic Chemistry
The first deoxygenative hydrosilylation of ketones promoted by samarium diiodide and samarium has been reported. In this approach, secondary alkyl silanes are synthesized from unactivated ketones and chlorosilanes in one step. The carbonyl group of ketones is activated by SmI2-mediated single-electron transfer process, which follows a deoxygenative ...

Samarium Diiodide/Samarium‐Mediated Deoxygenative Hydroborylation of Aldehydes

European Journal of Organic Chemistry
AbstractA samarium diiodide/samarium‐mediated direct deoxygenative hydroborylation of aldehydes with hydroborate ester has been reported. In this method, unactivated aldehydes and hydroborate ester have been employed as starting materials for the synthesis of primary alkyl borate esters.

Photodisintegration of samarium

Il Nuovo Cimento, 1956
In order to study the photodisintegration of Sm induced by irradiation with X-rays, discs of pressed Sm2O3 were exposed to the irradiation with X-rays from the 22 MeV Betatron of the Laboratrio de Fisica Nuclear of the University of Sao Paulo. In the present paper the results of the experiments are related.

A Study of the Hyperfine Structure of Samarium-153 and Samarium-155

1964
It was the purpose of this investigation to study the hyperfine structure of the β-unstable isotopes of samarium using the atomic beam magnetic resonance technique. A brief review is given of the nuclear and atomic theory necessary for the interpretation of the experiments. The hyperfine interaction constants (Mc/sec) for Sm153, and the nuclear moments
