Cell: Structure and Functions
Under certain circumstances, a nucleus can decay by emitting a particle more massive than an -particle. Consider the following decay processes:
Calculate the Q-values for these decays and determine that both are energetically allowed.
Solution: (i) In case of first process,
The mass defect occured in reaction is,
So, the amount of energy released is given by:
(ii) Now, in case of second reaction,
Mass defect is given as:
the Energy released in the reaction is:
Since both reactions have positive Q-value so both reactions are possible.
