    Magnetic moment of a deutron is 0.8574 u_n

    The magnetic moment of a deutron is 0.8574 u_n.Its ground state wave function is taken to be a mixture of S and D states.the expectation values of z-component of the magnetic mment in pure S and pure D states are 0.8797u_n and 0.3101u_n respectively.What is he contribution of the D state to the...

    What is the Minimum Energy Required for Photon-Induced Pair Production?

    I'm getting the photon momentum in CM frame to be zero( cos Center of mass is nucleus and its at rest in CM frame?)hows that possible!?

    What is the Minimum Energy Required for Photon-Induced Pair Production?

    Okay is the energy of initial photon energy in Cm frame 2mc^2 + Mc^2?(I haven't really many solved problems in center of mass frames so I'm finding it a lil difficult )but then how do I get momentum of photon? the momentum of all three particles are zero in CM frame.

    What is the Minimum Energy Required for Photon-Induced Pair Production?

    Homework Statement To show that the minimum energy a photon must have to create an electron-positron pair in the presence of a stationary nucleus of mass M is 2mc^2[1 + (m/M)], m is the electron rest mass. Homework Equations Conservation of energy and momentum.Also the minimum energy a...

    What Happens When Interfering Polarized Light Waves in X and Y Directions?

    I guess I did not frame my question clearly.What I meant is this: Consider the double slit experiment, where in you get an interference pattern on the screen. Suppose the two beams from the slits were polarised in orthogonal direction, in what way would it change the interference pattern? Would...

    What Happens When Interfering Polarized Light Waves in X and Y Directions?

    What happens if two waves polarised in the x and y direction , say, interfere? Will the interference pattern be of less intensity? Or will there be a sharper pattern?

    Which Differential Equation Does a Finite Wave Train Follow?

    Ok so what if i haven't specified that the shape changes or not? I thought the schrodinger's eqn was like the universal wave equation of sorts!

    Which Differential Equation Does a Finite Wave Train Follow?

    Suppose I have a FINITE wave train, ( of an unspecified nature), and it propagates along say the positive x-axis with a constant speed v and without any change of shape. Now which differential equation it MUST satisfy? The normal wave equation or the Schrodinger's equation?

    Shield Principle Clarified: Inside-Outside Electric Field Independency

    Consider an uncharged spherical conductor .It has a cavity carved out of it and there's a charge q in the cavity.Now you get an electric field outside the sphere.All fine.But why does Feynman say that "...no static distribution of charges inside a closed conductor can produce any fields...
