Question

A beam of 7.00-MeV protons is incident on a target of 27 13 Al. Those protons that collide produce the reaction shown below. p + 27 13 Al → 27 14 Si + n 27 14 Si has a mass of 26.986721 u. Neglecting any recoil of the product nucleus, determine the kinetic energy of the emerging neutrons.
