b.
The reaction e+ + --> p + is not allowed.
c.
Absorption of radiation in a material is a random process.
d.
Consider two absorbers made from the same material. Absorber B has twice the thickness as absorber A. Absorber B absorbs twice as much radiation as absorber A.
e.
The reaction p + n --> + + is not allowed.
a.
The reaction e+ + e- --> p + p(bar) is allowed?
b.
The reaction e+ + --> p + is not allowed.
c.
Absorption of radiation in a material is a random process.
d.
Consider two absorbers made from the same material. Absorber B has twice the thickness as absorber A. Absorber B absorbs twice as much radiation as absorber A.
e.
The reaction p + n --> + + is not allowed.
Explanation / Answer
statement d is false, as there is no such relation.
statement c is true.
state e is true because p + n --> + + is not allowed, p + --> + + n is allowed,
similarly statement a and b are also true.
