    Can You Solve These Differential Equations with Constants and Functions?

    Hi! I need your help for solving a couple of differential equation: dX/dt = a - b*X dY/dt = b*(c*exp(-E) - Y) - d*exp(-E)*Y X = X0 + f(Y, E) with X0, a, b, c and d are constants and f, a function of Z and E. Thank you in advance

    High School Angular distribution to energy distribution

    Hi! I wonder, in the case of elastic reactions with nuclear potential, how go from an angular distribution to an energy distribution? I have relationships on differential angular cross sections for neutron and proton elastic nuclear reations and I would like to transform them into differential...

    Undergrad Can phase shifts δl be calculated in scattering theory?

    Hello, My question is about the calculation of phase shifts δl in scattering theory. Some article mention that we can obtain phase shifts by numerically solving the radial Schrödinger equation but I'm not sure how to do it. Do you know how to proceed? is there any code (python, c ++, ...)...

    Undergrad Difference between binding energy and ionization energy

    Hi! I wonder since some time why ionization energies are not equal to binding energies. For instance, take the case of aluminum in the following configuration [Ne]3s²3p Ionization energy ~ 6 eV Binding energy ~ 5 eV Where does this difference come from ? Thanks in advance

    Fourier transform of the ground state hydrogen wave function

    Thanks for your reply mjc123 ! I had applied your recommendation and I find the result in (1.3) :wink: If I used the substitution u = cosθ, I must then integrate between 1 and -1 (cos(0) = 1 and cos(pi) = -1). I put du = -sinθdθ, so : exp(-i pr cos(θ) ) sin(θ) dθ = -exp(-i pr u) du = -...
