Heat some oil in a large cast iron pan over medium-high heat. Sear each side of the roast for 3 to 4 minutes or until it is browned on all sides. 1  Alternatively, use a Dutch oven for the entire process. 2  Sear the roast inside the Dutch oven on the stove.lace the meat on the grill. Transfer the seasoned roast to the unlit portion of the grill. Cover the grill and cook for 1 hour. 1  Stick a meat thermometer into the center of the sirloin tip roast to test its internal temperature.
Definition: Electron capture is a type of radioactive decay where the nucleus of an atom absorbs a K or L shell electron and converts a proton into a neutron. This process reduces the atomic number by 1 and emits gamma radiation and a neutrino.
Auger Electrons. 1. Ionization: A hole in an inner shell (here: K shell) is generated by an incident high-energy electron that loses the corresponding energy E transferred to the ejected electron.* 2.Auger-electron emission: The hole in the K shell is filled by an electron from an outer shell (here: L2).The superfluous energy is transferred to another electron which is subsequently ejected (here: from the L3 level) as Auger electron.ince Auger electrons have an energy in the range of some 100 eV to a few KeV, they are strongly absorbed by the specimen. Consequently, only Auger electron from the surface can be measured, making Auger spectroscopy a surface method. * Energy losses of the incident electrons are measured by EELS.
