OscSNS: Precision Neutrino Measurements at
... The flagship cross section analyses of OscSNS are the elastic scattering νee-→ νee- (NC and CC), NC νµe-→ νµe-, NC anti-νµe-→ antiνµe-, NC νµC→ νµC, and the CC νe12C→e-12N interactions. The current world's best measurement of the νee-→ νee- interaction arises in a sample of only 191 events [6], and ...

The Quantum Theory of Atoms - Electrostatics and Vibrations
... To overcome the loss of amplitude due to friction and air-resistance when, for example, pushing a swing, we often tend to give it periodic jolts ⇒ driven SHM. Consider pulling down a mass attached to the ceiling by a spring and letting it go while the fixture is itself made to vibrate at a certain f ...
