During a negative beta -decay
In negative beta decay :-
If a nucleus ._(Z)^(A)x emits one alpha -particle and one beta (negative beta ) particle in succession, then the daughter nucleus will have which of the following configurations?
fill in the blank to make the statement true. When we divide a negative integer by a positive integer, we divide them as whole numbers and put a _____ sign before quotient.
Consider the decay of a free neutron at rest: n top+e^(-) Show that the tow-body dacay of this type must necessarily give an electron of fixed energy and, therefore, cannot for the observed continous energy distribution in the beta -decay of a neutron or a nucleus.
.^(40)K is an unusual isotope, in that it decays by negative beta emission, positive beta emission, and electron capture. Find the Q values for these decays.
Staements I: ._zX^4 undergoes 2 alpha -decays, 2 beta -decays (negative beta ) and 2 gamma -decays. As a result, the daughter product is ._z-2X^(A-B) . Staements II: In beta -decay, the mass number decreases by 4 unit and atomic number decreases by 2 unit. In beta -decay (negative beta ), the mass number remains unchanged and atomic number increases by 1 unit. In gamma -decay, mass number and atomic number remain unchanged.
