<span>Answer is: an alpha particle.</span>
<span>Nuclear reaction: ¹</span>⁶O + p⁺
→ ¹³N + α (alpha particle).<span>
Alpha decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
When oxygen-16 gain one proton, atomic mass is 17, but when lose alpha particle
atomic mass reduces by four to 13.</span>
inital velocity (u) should be less
Butyl group is CH3 CH2 Ch2 CH2 -
Methyl group is CH3 -
Pentane is CH3 CH2 CH2 CH2 CH3

You can realize that there is a chain of 8 Cs (I bolded it).
The proper name must use the longest C chain; i.e octane.
In this case, there are 3 methyl groups attached to the 8 Cs chain, and they are at 2, 3 and 4 positions. Therefore, the name is:
2, 3, 4 trimethyl - octane
