The level structure of 14 B should be studied further. I am indebted to Prof. F.C. Barker for his comments. c See reaction 2.

It is assumed to be (5 ± 3)% in the calculation of the branching ratios to 14 C* (6.09, 6.73). d E -(max)= 14.0 ± 0.7 MeV to this state. e This branch has not been observed: the upper limit is shown. In the calculations of the branching ratios to 14 C* (6.09, 6.73) a value (5 ± 5)% was used. 6
