11. Using geometry, a slant intersection with this shell model can be determined and a vertical TEC measurement inferred. 12. This description turned out to furnish the shell model basis of the elegant and successful interacting boson model. 13. The first shell model was proposed by Dmitry Ivanenko ( together with E . Gapon ) in 1932. 14. In the shell model for the nucleus, magic numbers are the numbers of nucleons at which a shell is filled. 15. But two types of nuclei created in the Argonne experiments have revealed features that are inconsistent with the spherical shell model . 16. The SHELL model adopts a systems perspective that suggests the human is rarely, if ever, the sole cause of an accident. 17. On the other hand, however : The nucleons are not in close-packing, but organized as described by the nuclear shell model . 18. See nuclear structure and nuclear shell model . "'Sp in ni ng Spark "'12 : 35, 31 December 2009 ( UTC) 19. In atomic nuclei, the spin-orbit interaction is much stronger than for atomic electrons, and is incorporated directly into the nuclear shell model . 20. Each component of the SHELL model ( software, hardware, environment, liveware ) represents a building block of human factors studies within aviation.
