If the reaction is forbidden by all interactions explain why: -+ a. pn++μ+ +μ¯ b. Aºp+e¯ c. μ΄ →e + V d. p+p→y+Y e. Kºn++ π + π° +7° f. π+pAº + Kº g. Aºn+p h. pnº+e+ + ve i. n→p+e+V₂

A beam of 8.47-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.  Answer:_____MeV   Sorry the formatting is kinda off, im not sure how to fix it. Thank you!
