Abstract

The ¹⁴C(p, t)¹²C reaction leading to the states in ¹²C in the region of excitation energy E_x = 0-19 MeV was studied at E_p = 40.3 MeV. The data were analyzed within the framework of exact-finite-range first and second-order DWBA calculations using Op-shell-model wave functions. The transitions to the T = 0 states of natural parity were found to require 3 times more enhancement than those to the T = 1 states. Angular distributions of cross sections for the 1⁺ states were reproduced by including two-step processes such as (p-d-t) and (p, t) (t, t'), but their absolute values were underestimated in the present analysis. The (p, t) transitions to the 3^- and 4⁺ states, which are forbidden by the direct pickup process in the Op-shell-model space, were also investigated. The transition to the α-cluster-like 7.65 MeV 0⁺₂ state was explained reasonably by a multistep process via the 4.44 MeV 2⁺ state of ¹²C.
