    摘要: The invention relates to a method for enriching hyperpolarized nuclei. According to the inventive method, hyperpolarized atomic nuclei flowing in a gaseous mixture are dissolved in a solvent which is cooled at less than 293 K. A device for carrying out the method comprises at least one chamber with means for the degassing of hyperpolarized atomic nuclei which are dissolved in a solvent which is located in the chamber. The device comprises means for forming a magnetic field of 0.04 T maximum. Die Erfindung betrifft ein Verfahren zur Anreicherung von hyperpolarisienen Atomkernen. Das Ver-fahren sieht vor, in einem Gasgemisch stromende hyperpolarisierte Atomkeme in einem unterhalb 293 K gekühlten Lösungsmittel zu lösen. Eine Vorrichtung zur Durchführung des Verfahrens umfasst mindestens eine Kammer mit Mitteln zur Entgasung von hyperpolarisiente Atomkemen, die in einem in der Kammer befindlichen Lösungsmittel gelöst sind. Die Vorrichtung umfasst Mittel zur Ausbildung eines Magnetfeldes von maximal 0,04 T.

    摘要: The invention relates to a method for the hyperpolarisation of atomic nuclei by means of optical pumps in a sample cell. Polarisation of an electron spin of an optically pumpable species, which is produced by means of laser light, is transferred to the nucleus spin of an atom which is to be hyperpolarisied. According to the invention, components of the mixture and/or other inert compounds for hyperpolarisation are guided in the sample cell such that the mixture does not come into contact with the inner wall of the sample cell, or does to a small degree. A device for carrying out said method comprises at least one means which guides the components of the mixture of non-optical pumpable species and nuclei which are to be hyperpolarisied, and/or other inert compounds for hyperpolarisation, into the sample cell (5) such that the mixture does not come into contact with the inner wall of the sample cell (5), or does to small degree. As a result, the wall can be prevented from sagging.
