AN INVESTIGATION OF THE Jπ=l+; T=l STATES IN 40Ca WITH THE (p,γ) REACTION
Chin. Phys. Lett. 1989, 6 (3):
In order to explore the Jπ=l+;T=l states in 40Ca between 11.0 and 12.0MeVJ which have been predicted recently, the measurements of the 39K(p,γ)40Ca reaction have been taken. Nine resonances appeared in the region Ep=2.7-3.8MeVJ and six of them corresponding to Ep =2749, 3085, 3135, 3202, 3417 and 3708ke were observed for the first time with the (p,γ) reaction. The spin, parity and isospin of the 11.083MeV state in 40Ca are determined to be Jπ=l+; T=l . The M1 transition strength B(M1) of this state from the ground state is 0.24μ20;. The result is qualitatively in agreement with the the oretical prediction.
