Solution to task 658 from Chertov´s for extramural stud

658. The nuclear reaction 14N (α, p) 17O is caused by an α-particle with kinetic energy Тα = 4.2 MeV. Determine the thermal effect of this reaction, if the proton, ejected at an angle ϑ = 60 ° to the direction of motion of the α-particle, received kinetic energy T = 2 MeV.
