The influence of elastic and inelastic collisions associated with the large ground-state s-wave scattering length of 40Ca was measured. From these findings, an optimized loading and cooling scheme was developed that allowed us to condense about 2\u00c3\u009710^4 atoms after laser cooling in a two-stage magneto-optical trap and subsequent forced evaporation in a crossed dipole trap within less than 3 s. The condensation of an alkaline earth element opens novel opportunities for precision measurements on the narrow intercombination lines as well as investigations of molecular states at the 1S-3P asymptotes.&#8221;<\/div>\n<div class=\"delicious-tags\">(tags: <a href=\"http:\/\/delicious.com\/orzelc\/science\">science<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/articles\">articles<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/physics\">physics<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/atoms\">atoms<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/optics\">optics<\/a> <a href=\"http:\/\/delicious.com\/orzelc\/low-temperature\">low-temperature<\/a>)<\/div>\n<\/li>\n<li>\n<div class=\"delicious-link\"><a href=\"http:\/\/physicsworld.com\/cws\/article\/news\/40475\">Particle feud goes public &#8211; physicsworld.com<\/a><\/div>\n<div class=\"delicious-extended\">&#8220;HARP ran in 2001 and 2002 but severe disagreements over the quality of data analysis within the group led to a split in 2004.
