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.
Electron configuration. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s2 2s2 2p6. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals. Mathematically, configurations are described by Slater determinants or configuration state functions.
