Which isotope, when bombarded with nitrogen-15, yields four neutrons and the artificial isotope dubnium-260?

Question

Quizplus · Accepted Answer

When nitrogen-15 ($^{15}N$) is bombarded onto californium-249 ($^{249}Cf$), the reaction yields dubnium-260 ($^{260}Db$) and four neutrons ($4n$). This can be represented by the equation: $$^{249}_{98}Cf + ^{15}_{7}N \rightarrow ^{260}_{105}Db + 4^{1}_{0}n.$$ This showcases the transmutation process leading to the formation of an artificial isotope through nuclear reaction.
