Unformatted text preview: A 43.51: Z X z + Z  1 Y ( Z 1) + + + Adding (Z 1) electron to both sides yields A A + + Z X Z 1 Y + So in terms of masses: A A m = M Z X +  M Z 1 Y  me A ( ( X)  m )  M ( Y)  m = M ( X)  M ( Y )  2m .

A Z e A Z 1 A Z A Z 1 e ( ) ( ) e So the decay will occur as long as the original neutral mass is greater than the sum of the neutral product mass and two electron masses. ...
