Question 6

In the upper atmosphere, high-energy cosmic ray neutrons collide with nitrogen-14 nuclei to produce carbon-14, which is vital for radiocarbon dating. The reaction is represented by the equation:

01n+714N→614C+Y {}^{1}_{0}\text{n} + {}^{14}_{7}\text{N} \rightarrow {}^{14}_{6}\text{C} + \text{Y} 01​n+714​N→614​C+Y

What is particle Y\text{Y}Y?

A

positron

B

electron

C

neutron

D

proton
