Deuterium H with kinetic energy K is red towards a stationary alpha particle (EHe) to form a lithium nucieus (gLi) according to the reaction ; He+ 35; gLiir Q , where Q gains energy and the nucleus gLi is in the lowest energy state (groundstate). If the rest masses of deuterium are md, alpha mEl and lithium mm, determine: (I). The value of Q if the formed core EU is at rest, (It). Nuclear binding energy of (EU) in problem No.0), (Ill). if after the nucleus reaction EU is in an excited state, explain whether the binding energies obtained in Problem No.(l) and Q in Problem No.(ll) are still valid, if not, give reasons to strengthen the arguments given
