XmlmmCIF equivalent: exptl Data items in the EXPTL category record details about the growth of the crystal, and about experimental measurements on the crystal, such as shape, size, density, and so on. XmlmmCIF equivalent: exptl/absorpt_coefficient_mu The absorption coefficient mu in reciprocal millimetres calculated from the atomic content of the cell, the density and the radiation wavelength. XmlmmCIF equivalent: exptl/absorpt_correction_T_max The maximum transmission factors for the crystal and radiation. These factors are also referred to as the absorption correction A or 1/A*. XmlmmCIF equivalent: exptl/absorpt_correction_T_min The minimum transmission factors for the crystal and radiation. These factors are also referred to as the absorption correction A or 1/A*. XmlmmCIF equivalent: exptl/absorpt_correction_type The absorption correction type and method. The value 'empirical' should NOT be used unless no more detailed information is available. XmlmmCIF equivalent: exptl/absorpt_process_details Description of the absorption process applied to the intensities. A literature reference should be supplied for psi-scan techniques. XmlmmCIF equivalent: exptl/crystals_number The total number of crystals used in the measurement of intensities. XmlmmCIF equivalent: exptl/details Any special information about the experimental work prior to the intensity measurement. See also _exptl_crystal.preparation. XmlmmCIF equivalent: exptl/method The method used in the experiment. XmlmmCIF equivalent: exptl/method_details A description of special aspects of the experimental method. XmlmmCIF equivalent: exptl/entry_id This data item is a pointer to _entry.id in the ENTRY category.
