Studying particle-hole excitation levels near closed nuclear shells enhances our understanding of single-particle properties and two-body interactions. Although the changes in nuclear of structure doubly magic and near doubly magic nucleus such as $^{4}$He, $^{16}$O, $^{40}$Ca, $^{4}$H, and $^{40}$K are well studied, information on charge-changing particle excitation states in $^{48}$Ca (T=5 negative parity states) has not yet been widely investigated.
To address this issues the $^{47}$K(${\it p}$,${\it p}$)$^{47}$K elastic scattering reaction in inverse kinematics was performed using the Array for Nuclear Astrophysics and Structure with Exotic Nuclei (ANASEN)[1] as an active target detector to study energy levels of low-lying negative parity T=5 states in $^{48}$Ca. Radioactive $^{47}$K beam from the ReA3 at National Superconducting Cyclotron Laboratory (NSCL) at energy of 4.6 MeV/u was delivered to CH4 gas target filled in ANANSEN. Excitation function for ${\it p}$+$^{47}$K elastic scattering reaction was measured from E$_{c.m}$ = 1 to 4.5 MeV. Narrow resonances in the excitation function are expected to identify the T=5 states in $^{48}$Ca. Details of the experiment and the preliminary results will be presented.
