Muffin-tin approximation Muffin-tin approximation The muffin-tin approximation is a shape approximation of the potential well in an crystal lattice. It is most commonly employed in quantum mechanical simulations of the electronic band structure in solids. The approximation was proposed by John C. Slater. Augmented plane wave method (APW) is a method which uses muffin-tin approximation. It is a method to approximate the energy states of an electron in a crystal lattice. The basic approximation lies in the potential in which the potential is assumed to be spherically symmetric in the muffin-tin region and constant in the interstitial region. Wave functions (the augmented

Disneyland Resort Paris 15th Anniversary The Disneyland Resort Paris 15th Anniversary Celebration was a year-long celebration event at the Disneyland Paris holiday resort in Marne-la-Vallée near Paris, France to mark fifteen years of operation. The events officially began on 1 April 2007, following a day of press events and premieres on 31 March 2007. The celebration was originally planned to end on 31 March 2008. However, the celebration was extended until 7 March 2009. The celebration was replaced by Mickey's Magical Party from 4 April
