Energy released, E = [ M( 231 X) + M(4He) - M(235Y)]c2

= [(7.835 x 231) + (7.07 x 4) - (7.8 x 235)]MeV

= [1809.9 + 28.28 - 1833]MeV

= 5.18MeV

= 5.18 x 1.6 x 10-13J

This entire kinetic energy is taken by Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.- particle as given.
