Hi Sunil

yes of course it was meant to be 10B(n,alpha)7Li

The confusion probably stemmed from 6Li(n,t)4He which is missing in the
list, so that 6Li(n,t)4He, 10B(n,alpha)7Li became 10B(n,t)4He
which obviously is nonsense. The mistake is repeated twice in the manual,
I am going to correct it

              Ciao
