Abstract Low-lying states in$$^{54}$$ Cr have been investigated via the$$\alpha $$ -transfer reaction$$^{50}$$ Ti($$^{7}$$ Li,t) at a bombarding energy of 20 MeV. The exclusive$$\alpha $$ -transfer channel is separated from other reaction channels through the appropriate energy gate on the complementary particle, triton. Levels of$$^{54}$$ Cr populated exclusively by the$$\alpha $$ -transfer process could be identified up to$$\approx $$ 5 MeV excitation energy and angular momentum up to$$(8)^{+}$$ , by identifying the corresponding known$$\gamma $$ -rays. These include multiple low-lying non-yrast 2$$^+$$ and 4$$^+$$ states, which would otherwise be unfavorable via fusion evaporation reactions. The feeding-subtracted$$\gamma $$ -ray yields have been extracted to estimate the population of various excited states through the transfer process. The measured integrated transfer cross sections for all the observed yrast and non-yrast states are compared with Coupled Channels calculations usingfrescoto extract the$$\alpha $$ +$$^{50}$$ Ti core spectroscopic factors. For the yrast states, a higher$$\alpha $$ +core overlap is seen for the$$2^+$$ and$$4^+$$ states, while it is seen to be less favorable for the$$6^+$$ and$$(8)^+$$ states when$$\alpha $$ -transfer is considered to occur predominantly as a direct one-step process to the$$^{50}$$ Ti core ground state. The yrast$$2^+$$ , and$$4^+$$ states are predominantly populated by single-step transfer, while for the states with spin$$\ge $$ 5, the possibility of core excitation followed by$$\alpha $$ -transfer shows a larger$$\alpha $$ -core overlap. For the non-yrast$$0^+$$ ,$$2^+$$ , and$$4^+$$ states, single-step transfer shows moderate to small$$\alpha $$ -core overlap. No higher spin non-yrast states are observed.more » « less
