Title: {alpha} cluster states in {sup 44,46,52}Ti

Abstract

{alpha} decaying states of {sup 44,46,52}Ti were investigated with angular correlation functions between t and {alpha} with the {sup 40,42,48}Ca({sup 7}Li,t{alpha}){sup 40,42,48}Ca reactions at E=26.0 MeV. Many {alpha} cluster states were newly observed in the 10-15 MeV excitation energy of {sup 44}Ti and their spin-parities were assigned, in which J{sup {pi}}=7{sup -} state was found at 11.95 MeV as a candidate for the member of the K=0{sub 1}{sup -} negative parity band. In {sup 46}Ti many {alpha} cluster states were also found in the 11-17 MeV excitation energy with the {sup 42}Ca({sup 7}Li,t{alpha}){sup 42}Ca reaction, though its strength is weak compared with {sup 44}Ti. No {alpha} cluster states were detected for the {sup 48}Ca({sup 7}Li,t{alpha}){sup 48}Ca reaction, in which the number of coincidence events decaying from {sup 48}Ca was very small.
