Need help with this question

It is requested to examine the first excited state of 160 with an energy of 6,049 MeV. a) What are the minimum arrival energies of the networks that will create these awakened states using the C(alpha,n) reaction? b) In which direction do the emitted neutrons move? c) If it is desired to detect neutrons emitted perpendicular to the direction of arrival, what would be the minimum alpha energy that could create this excited wave?
