# How to determine neutrino type [nuclear/particle phys]

A beam of negative pions enters a bubble chamber and triggers the following reaction and successive decays all take place within the bubble chamber:

$$\pi$$- + p $$\rightarrow$$ $$\Lambda$$0 + K0

$$\Lambda$$0 $$\rightarrow$$ $$\pi$$ + p
K0 $$\rightarrow$$ $$\pi$$+ + $$\mu$$ + $$\bar{\nu}$$ $$\rightarrow$$ e- + $$\nu$$ + $$\bar{\nu}$$

The question asks to determine the types on neutrinos in the K0 and $$\mu$$ decays, how do I do this? Do I assume, for example, that the electron neutrino always appears with the electron etc?
