rcb0dc22 r92dfe0c 4 4 5 5 Calculates the form factor for a rectangular solid with a core-shell structure. 6 The thickness and the scattering length density of the shell or 7 "rim" can be different on each (pair) of faces. However at this time 8 the model does **NOT** actually calculate a c face rim despite the presence of 9 the parameter. 10 11 .. note:: 12 This model was originally ported from NIST IGOR macros. However,t is not 13 yet fully understood by the SasView developers and is currently review. 6 **The thickness and the scattering length density of the shell or "rim" 7 can be different on all three (pairs) of faces.** 14 8 15 9 The form factor is normalized by the particle volume $V$ such that … … 41 35 V = ABC + 2t_ABC + 2t_BAC + 2t_CAB 42 36 43 **meaning that there are "gaps" at the corners of the solid.** Again note that 44 $t_C = 0$ currently. 37 **meaning that there are "gaps" at the corners of the solid.** 45 38 46 39 The intensity calculated follows the :ref:`parallelepiped` model, with the … … 99 92 detector plane. 100 93 94 Validation 95 ---------- 96 97 The model uses the form factor calculations implemented in a c-library provided 98 by the NIST Center for Neutron Research (Kline, 2006). 99 101 100 References 102 101 ---------- … … 113 112 114 113 * **Author:** NIST IGOR/DANSE **Date:** pre 2010 115 * **Converted to sasmodels by:** Miguel Gonzales **Date:** February 26, 2016 116 * **Last Modified by:** Wojciech Potrzebowski **Date:** January 11, 2017 117 * **Currently Under review by:** Paul Butler 114 * **Last Modified by:** Paul Butler **Date:** September 30, 2016 115 * **Last Reviewed by:** Miguel Gonzales **Date:** March 21, 2016 118 116 """ 119 117
