1.Two particles are attracted to each other by a force that is described by a

central potential, where q is a (dimensionless) constant, μ is the particles' reduced mass, and r is their

separation. The particles' wave function can be factored into radial and angular components,

where Yem (0, 0) is one of the standard spherical harmonics and Rne(r) is the radial wave

function for this system. For what values of the angular momentum quantum number,

I can this system have bound-state solutions?
