Is it possible for ""_(92)U^(238) spontaneously to emit a proton? Given, atomic mass of ""_(92)U^(238), ""_(91)Pa^(237) and ""_(1)H^(1) is 238.05079 u, 237.05115 u and 1.00783 u respectively.

The number of protons and neutrons left in ""_(92)U^(238) after emission of an a-particle are

In the transformation of ""_(92)""^(238)U to ""_(92)""^(234)U , if one emission is an alpha particle, what should be the other emission(s)?
