Solution of Schrodinger equation under a repulsive Coulomb potential?

Is there any reference on how to solve the radial part of the Schrodinger equation under a repulsive 1/r potential? There will be no bound states, but how to find the exact wave functions??

Can anyone help with diagonalization of matrices by biunitary transformation?

If I understand correctly, then any matrix can be diagonalized with real and +ve diagonal entries via a bi-unitary transformation. My question is, given a matrix, are the unitary matrices unique??...

What does it actually mean, when one says that the differential scattering cross section blows up in the forward direction?

Suppose we place a detector in the forward direction (practically not possible) to collect the scattered particles only. Will it collect infinite no. of particles for a finite incident flux? Am I...

Is there any problem with a fermion singlet within the Standard Model?

By 'singlet' I mean SU(2) singlet, i.e. a charged fermion without its partner. Is there any theoretical drawback? As I think, it will have no coupling with the Higgs, since Higgs is not needed to...

Can you connect an HPLC to a Mass Spec only at a certain time point?

Can anyone explain this method? Especially the last statement where it says only at 1.5 to 2.5mins was the MS/MS connected to the UPLC. How is that possible, is it a feature in this specific...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

How are iso-frequency contours plotted?

Let's say we have a standard, regular hexagonal honeycomb with a 3-arm primitive unit cell (something like the figure attached; the figure is only representative and not drawn to scale). The...

Is artifacts in XPS possible to build high deviation in binding energy larger than 5 eV??

Hello. Thanks for your consideration to see my question. Recently, I conducted XPS anaylsis of g-CN that is prepared from thermal polycondensation of DCDA, so-called conventional bulk-g-CN,...

If you are only interested in the top loop part then this is almost identical to H --> 2 x gluon or even Higgs production via gluon fusion. For this you could look at the paper in the link below.

Yes, I am mainly interested in the top-loop. Thanks for the help.
