Neutron Pickup Reactions on ${Si}^{30}$

The neutron pickup reactions

{Si}^{30} (d, t) {Si}^{29}

and

{Si}^{30} ({He}^{3}, α) {Si}^{29}

have been studied. The results indicate that the neutron configuration of

{Si}^{30}

contains about equal components of

1 d_{\frac{3}{2}}

and

2 s_{\frac{1}{2}}

neutrons. A small

f

-wave neutron component in the ground-state wave function was also found. Strong transitions with

l = 2

J^{π} = {\frac{5}{2}}^{+}

were observed to levels at 2.03, 4.89, 6.72, and 8.32 MeV. The latter is probably the isobaric analog to the ground state of

{Al}^{29}

. The level at 4.08 MeV was not excited. The results are compared with the neutron stripping reaction

{Si}^{28} (d, p) {Si}^{29}

and with experiments on the

γ

decay of the states of

{Si}^{29}
