| 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.
