## Homework Statement

What relations can you derive from isospin conservation for the cross sections of the following scattering processes:

K[itex]^{+}[/itex] + p → K[itex]^{+}[/itex] + p

K[itex]^{+}[/itex] + n → K[itex]^{0}[/itex] + p

K[itex]^{0}[/itex] + n → K[itex]^{0}[/itex] + n

## The Attempt at a Solution

I do not really have my own solution as I've just started learning this, and fail to understand the question: I do not necessarily need the answer, but a starting tip and an explanation of the question at hand would be much appreciated!
